Subject: [PATCH 06/23] staging: rtl8188eu: remove all RT_TRACE calls from core/rtw_security.c

Remove all RT_TRACE calls from core/rtw_security.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.
