Subject: [PATCH v2 3/4] staging: r8188eu: remove HAL_DEF_CURRENT_ANTENNA

In order to get rid of the function GetHalDefVar8188EUsb(), remove
the HAL_DEF_CURRENT_ANTENNA case from it and move the functionality
into a new function. This is part of the ongoing effort to get rid of
the unwanted hal layer.

Signed-off-by: Michael Straube <straube.linux@...il.com>
---
v2:
- added rtw_ prefix to the function name
- added the function in rtw_mlme.c
