[PATCH 2/5] staging: r8188eu: merge rtw_os_recvbuf_resource_alloc() into rtw_recv.c

[Michael Straube <straube.linux@gmail.com>]

Merge the functionality of the function rtw_os_recvbuf_resource_alloc()
into rtl8188eu_init_recv_priv(). Merging the functionality instead of
just making the function static improves readability and we have one
function less to care about when converting the uses of _FAIL/_SUCCESS
to normal kernel error code logic.
