present: If present_queue_vblank() fails, do present_execute().
Previously, if present_queue_vblank() failed, we simply dropped the present request on the floor, and returned an error. This was rather mean to clients - after presenting, they wait for a PresentComplete event to come back. But since the present never happens, they end up waiting forever, and lock up in poll(). This patch falls back to present_execute if present_queue_vblank fails. We still print a debugging message to warn when queueing fails, which allows us to continue debugging problems, but makes Present robust enough to not lock up people's compositing manager when vblank bugs happen. v2: Don't do present_queue_vblank() /and/ present_execute() (a bug that snuck in during last minute tidying).
