msm_fb: display: commit BLT to mdp register during video kickoff

BLT (writeback mode) need to be committed to mdp register
before kickoff. Normally, UI kickoff will follow immediatly
after BLT enabled/disabled. However sometimes video overlay
play happen before UI's pan display after BLT enabled/disabled.
In this case, video kickoff need to commit BLT to mdp register too.
