Subject: [PATCH 11/57] staging: rtl8723bs: core: rtw_mlme_ext: Deal with a bunch of unused variables

Some are used inside debug prints.  These get marked as __maybe_unused.

Others are used within #ifery.  These are defined inside the same #ifery.

Lastly, ones that are truly unused are removed entirely.

Fixes the following W=1 kernel build warning(s):

 drivers/staging/rtl8723bs/core/rtw_mlme_ext.c: In function ‘OnAssocReq’:
 drivers/staging/rtl8723bs/core/rtw_mlme_ext.c:1058:17: warning: variable ‘reassoc’ set but not used [-Wunused-but-set-variable]
