Subject: [PATCH v2 2/2] staging: rtl8192u: remove redundant macro definition

Several ieee80211_* symbol names are extended with _rsl tag using
macros. This is done to avoid a conflict when a similar symbol is
already in use in another part of kernel and may lead to conflicts.
However, most of these base symbol names are not found to being used
anywhere in the code and hence are not useful today. These symbols
are not used outside of the module and hence can be safely removed.
The code continues to use the original symbol names.

Changes in v2:
   1. Review other similar macro defines and clean those up as well.

   2. Revise patch log to explain impact of the patch
