[PATCH 3/5] staging: r8188eu: remove HW_VAR_CHK_HI_QUEUE_EMPTY from GetHwReg8188EU()

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

The HW_VAR_CHK_HI_QUEUE_EMPTY from GetHwReg8188EU() just calls
rtw_read32(). Remove HW_VAR_CHK_HI_QUEUE_EMPTY from GetHwReg8188EU()
and call rtw_read32() directly. Move the call to a new function to
indicate what it actually does. This is part of the ongoing effort to
get rid of the unwanted hal layer.
