Yashwanth 811402fc83 disp: msm: sde: hold vmlock only during transition in check phase ...

In the current code, vmlock is always acquired in check
phase even if there is no transition between vm's. This
might result in janks if vmlock is held concurrently by
other processes such as backlight update. This change
ensures that vmlock is held only if there is a valid
transition request between vm's in check phase.

[cohens@codeauarora.org] Resolved trivial merge conflict
and refactored the code to reduce the code complexity.
