Increment and decrement pending_flips only for flips, not blits
When a display is not flippable, OMAPDRI2ScheduleSwap falls back to
a blit, which causes switch to blit mode, which waits for all flips
to complete based on pending_flips counter which was incremented before
the decision was made whether to flip or fall back to blit causing a
deadlock. This change moves the pending_flips increment after the
decision is made to do the flip and only decrements it for completed
flips not blits.
BUG=chrome-os-partner:23877
TEST=move primary display to HDMI monitor, start playing a video, close
and open lid repeatedly.
