ecore_drm2: Better handle flip failure 

We need to release the buffer we couldn't flip to when a flip fails.

This makes whatever bug is causing a page flip to happen right after
dpms blanks the screen, which was leading to a failure to ever wake
from dpms because the flip left a pending buffer that never completed.

Fix T5462
