[PATCH 1/9] staging: r8188eu: remove HW_VAR_RESP_SIFS from SetHwReg8188EU()

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

SetHwReg8188EU() is called with HW_VAR_RESP_SIFS only in one place.
Remove the HW_VAR_RESP_SIFS case from SetHwReg8188EU() and call
rtw_write8() directly instead. This is part of the ongoing effort to
get rid of the unwanted hal layer.
