kernel - Fix i915 deadlock
* (Attempt to) fix a deadlock in the i915 code. The device lock retry
code does not release the PG_BUSY on the passed-in placeholder page,
so the fact that the lock is obtained non-blocking is irrelevant.
Try to fix this by immediately releasing the placeholder page. The
code already checks for an insertion race later on.
