hwc: mdpcomp: one full screen update in screen refresh
When screen refresh is triggered, make sure at least one
full screen update when partial update is enabled.
Screen refresh is requested after post processing has been
sent to kernel, full screen update is needed so that the
pp setting applies to the whole screen.
