Subject: [PATCH 9/9] staging: r8188eu: remove HW_VAR_BCN_VALID from SetHwReg8188EU()

The HW_VAR_BCN_VALID case in SetHwReg8188EU() just calls rtw_write8().
Remove HW_VAR_BCN_VALID from SetHwReg8188EU() and call rtw_write8()
directly. This is part of the ongoing effort to getrid of the unwanted
hal layer.
