msm: mdss: Don't schedule pp done work during on going commit

Browse source 
Function mdss_mdp_ctl_perf_get_transaction_status tracks mdp
status whether a commit is currently in progress. If it is
then we don't schedule the work queue, otherwise schedule it.
Cases where work queue is not scheduled, waitforpp takes care
of notify frame done. In case of last frame update, work
queue takes care of notify frame done.
