msm: mdss: wait for one commit transfer for command mode after resume 



In command mode, the backlight level is set before the first commit
is completed. It shows a snowy screen after suspend resume. Wait for
one ping pong done to ensure commit is completed after suspend
resume before backlight level is set.
