xmitframe_swencrypt always returns _SUCCESS and the caller does not check
the return value. We can remove the return value and make
xmitframe_swencrypt a void function.

In function xmitframe_swencrypt, we can return immediately if our packet
needs no encryption. This is simpler than wrapping all the code into a
large if statement.

All callers of rtl8188eu_xmitframe_complete set the pxmitbuf parameter to
NULL, in which case rtl8188eu_xmitframe_complete allocates another
xmit_buf internally.
Remove the pxmitbuf parameter and resulting dead code.

rtl8188eu_init_xmit_priv's only jobs is to initialise the xmit tasklet.
Remove rtl8188eu_init_xmit_priv and initialise the xmit tasklet in
_rtw_init_xmit_priv. Yet again, this makes the code a tiny bit smaller.

We do not need the psta check in the while loop of rtw_xmitframe_coalesce.
psta is already checked near the start of the function and is not modified
afterwards.

Reorder the code in rtw_make_wlanhdr to make the function simpler.
There's a large if statement to check that we process only data frames.
Revert the condition and exit for non-data frames.

Simplify the error handling in rtw_make_wlanhdr. Exit immediately instead
of jumping to the end of the function. We don't have to do any clean-up.

The qos_option variable in function rtw_make_wlanhdr should be a boolean
as it's set to true or false. We can directly set it to
pqospriv->qos_option instead of using a default value and if statements.

The bpending array in struct xmit_buf is unused. Remove it.
(struct xmit_buf is not part of the interface between the kernel driver and
the device's firmware. It's safe to remove components from this struct.)

There's no need to call rtw_free_xmitframe before we dequeue the first
frame. pxmitframe is always NULL at this point, rtw_free_xmitframe will do
nothing in this case.

The _rtw_init_xmit_priv function calls rtw_alloc_hwxmits to allocate
memory for pxmitpriv->hwxmits (this is an array of struct hw_xmit). This
allocation uses kzalloc, the allocated memory is initialised with 0.
After the allocation, _rtw_init_xmit_priv calls rtw_init_hwxmits to set an
element of each hw_xmit to 0. This is not necessary, we can remove the
rtw_init_hwxmits call and the now unused function rtw_init_hwxmits.

struct xmit_priv contains a pointer to an array of struct hw_xmit entries.
xmit_priv's (ill-named) hwxmit_entry component stores the size of this
array, i.e. the number of hw_xmit entries that are used.
The array size is constant, it's initialised to HWXMIT_ENTRY and never
updated. Simplify the code accordingly. Remove hwxmit_entry, do not pass
the array size as a function parameter and use HWXMIT_ENTRY in the code
that handles the array.
