Don't lower the ipl when returning from handling an interrupt.
If the ipl is lowered here, a machine can rapidly run out of stack
space when it is under heavy interrupt load. Without this fix,
my test machine would fall over within a few seconds when forwarding
14,000 packets/sec. With the patch, it has been up for over 24 hours
and has built the world at the same time.
