Log message:
Since we now have an attachhook, the actual interrupt handler is installed
late, after we enable interrupts. If the interrupt pin used for inteldrm(4)
is shared with another device, we may end up being called before the actual
interrup handler is installed resulting in a null-pointer dereference.
Fix this by adding an explicit check that the interrupt handler function
pointer has been set.
