qcacmn: Avoid timer double free when disable scheduler

A global timer is created and freed by each module, if passed as
msg to mc queues, shouldn't be freed in scheduler_cleanup_queues,
or double free issue happens

For example, a timer in tLimTimers is freed in mac_stop->pe_stop
->lim_cleanup_mlm
