uxa: Restore old bo on failure
When we fail to do a modeset, we need to make sure that we restore the
previous bo in the event that it's changed. Otherwise we'll crash the X
server the next time we do a pageflip.
This fixes an issue with panning crashing the X server if a user tries
to set a large panning resolution such as 5200x3200, and the GPU doesn't
have enough memory to handle the bo due to being in UXA mode.
