Merge from RELENG_5: 1.19.2.2

Some changes to intr_execute_handlers():
- Fix NULL pointer dereferences caused when an ithread or a handler is
  NULL which happens when a stray interrupt triggers after the respective
  device interrupt was torn down.
- Remove the critical section around INTR_FAST handlers which actually
  was a nested critical section. Both tl0_intr() and tl1_intr() already
  enter a critical section for calling intr_execute_handlers().
