staging: r8188eu: remove GetHalDefVar8188EUsb()

The local variable odm_flag in rtw_dbg_port() is set but never used.
This are the last two remaining calls to GetHalDefVar8188EUsb(). Both
calls can be removed and we finally can remove GetHalDefVar8188EUsb()
itself. This is part of the ongoing effort to get rid of the unwanted
hal layer.
