Description:
While performing out of buffer release processing we can
simultaneously try to release pages due to a received
FIRE_TRIG_ORD.

How to repeat:
test_event -r 5000 -n Bug30780 T1

Suggested fix:
Introduce state checking if out of buffer release is ongoing,
if so skip releasing pages from do_FIRE_TRIG_ORD.
