Revert "msm: mdp: Update sync pt. behaviour"

This reverts commit 168c1467873fd46f25ee5cee553e2959fc99ef2d.
msm: display: command mode panel release fence

For command mode panel, release fence should be signaled after the buffer is
sent to the panel.  For performance consideration, allow one more commit to be
queued.  Keep the second kick off as short as enough.
