wlan: Enabling MTRACE logs in PE module

MTRACE is a comprehensive logging mechanism which captures all
the events entering and exiting the PE module in both the northbound
and southbound interfaces.This also records all the timers activity
and state machine changes.MTRACE support is present in our driver since
long time but its not being used.So now these changes are to enable the
MTRACE logging mechanism already present in the PE module and make it work.
