Subject: [PATCH 6/7] 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.
