Subject: [PATCH 5/5] staging: r8188eu: remove GetHwReg8188EU()

The only call to GetHwReg8188EU() that is left over from previous
cleanups sets a variable that is immediately overwritten. This call
is useless and we can finally remove the GetHwReg8188EU() function.
This is part of the ongoing effort to get rid of the unwanted hal
layer.
