[PATCH 09/23] staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_mlme.c

From: Phillip Potter
Date: Thu Jun 24 2021 - 20:08:48 EST

Remove all RT_TRACE calls from core/rtw_mlme.c as this macro is
unnecessary, and these calls are dubious in terms of necessity.
Removing all calls will ultimately allow the removal of the macro
itself.

Also remove rtw_atimdone_event_callback and rtw_cpwm_event_callback
functions and their associated header declarations/usages, as all
they do is call RT_TRACE and nothing else.
