[PATCH v7 16/19] staging: r8188eu: clean up rtw_read*() and rtw_write*()

Clean up rtw_read{8,16,32}() and rtw_write{8,16,32,N}() in usb_ops_linux.c.

1) Rename variables:
length => len
pio_priv => io_priv
pintfhdl => intfhdl
wvalue => address.
2) Remove unnecessary casts.
3) Fix types. Use __le16 instead of __le32.
