fbdev: msm: Increment commit count in case of ESD recovery 



In case of ESD recovery an early return is performed for commit.
Due to this commit count in not incremented and pending fences
are signaled. This is resulting in UI corruption because of
premature fence signaling after ESD recovery is performed.

Fix issue by incrementing commit count in case of ESD recovery.
