[PATCH] staging: rtl8723bs: core: rtw_mlme_ext.c: Remove set but unused variable

Removed set but unused 'reason_code' variable. Issue detected by GCC
running with the warning option -Wunused-but-set-variable. Removed its
use as a storage of the return value of get_unaligned_le16(), which has
been left as is because it has side effects on the argument it takes.
