disp: msm: sde: retry preclose commit in cases of -ERESTARTSYS

Browse Source 
This change allows the commit in preclose to be attempted a
number of times in the event that the return value is -ERESTARTSYS.
This can happen if there is some timing delay which is preventing
the commit to go through completely and an error code is returned.
