Subject: [PATCH 5/9] staging: r8188eu: remove HW_VAR_RXDMA_AGG_PG_TH from SetHwReg8188EU()

The HW_VAR_RXDMA_AGG_PG_TH case in SetHwReg8188EU() just sets a
variable conditionally and then calls rtw_write8(). Set the variable
in the caller and, call rtw_write8() directly and remove the
HW_VAR_RXDMA_AGG_PG_TH case from SetHwReg8188EU(). This is part of the
ongoing effort to get rid of the unwanted hal layer.
