qcacld-3.0: Cleanup MLM state machine in pe_close

Currently host cleans up lim timers in lim_cleanup_mlm
before scheduler_disable is called, so if scheduler schedules
scheduler_qdf_mc_timer_callback_t_wrapper before
lim_cleanup_mlm and this callback is executed before
scheduler_disable then host will try to start an
uninitialized timer.
To address this issue call lim_cleanup_mlm from pe_close
as pe_close is called after scheduler disable.
