msm: mdss: Don't call pan_idle for MSMFB_OVERLAY_PREPARE ioctl
We keep calling MSMFB_OVERLAY_PREPARE for each composition
cycle, even if there are no changes in params. Because of this
we can hit performance degradation due to pan idle wait.
This change removes pan_idle wait for prepare call.
Original fix change id: Ie99f4dbc4671caf9bfbd49bd9b200c3180002d56.
As it was broken through a refactoring change, correcting it now.
