OMAP DSI: Fix consecutive bus unlocks for manual mode panel.
Description: In manual mode panels, a semphore is used to keep track
of display queue and release. Upon the condition of framedone timeout
error the semaphore is released once by the callback handler before exiting.
If framedone for the timed-out frame arrives after 250 msec and before
next frame queuing, it releases the semaphore second time in the callback handler.
This results in warnon assert later.
This patch puts in proper check before releasing the semaphore.
This way we prevent multiple unlocks of the bus..
