staging: r8188eu: simplify rtw_get_ff_hwaddr

On both occassions where rtw_get_ff_hwaddr is called, the result is used
as addr parameter for rtw_write_port. rtw_write_port only needs the info
if the high queue was used or not. Simplify rtw_get_ff_hwaddr accordingly
and remove the now unused queue defines.

staging: r8188eu: simplify xmit_buf flags

rtw_write_port stores a queue index in pxmitbuf->flags before submitting
an urb. The urb completion function reads the flags. All it needs is the
info if the high queue was used or not.

We can replace the flags with a boolean high_queue variable.

staging: r8188eu: we use a constant number of hw_xmit entries

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.

The second argument of rtl8188e_set_FwMediaStatus_cmd() needs to be in CPU
order, not little-endian; however, when it uses that value to call
FillH2CCmd_88E() the parameter must be in little-endian order as that
value will be sent to the firmware. Note that the conversion from LE to CPU
order was le16_to_cpu() rather than the correct cpu_to_le16.

The definition of FillH2CCmd_88E() is revised, and the proper conversion
routine is used.

Note that the original code performed one byte swap on the secong argument
of FillH2CCmd_88E(), and got the correct answer even though the semantics
were very wrong.
