Fix nasty crashes on IP22 machines with console running at 38.4kbps (which
generally translates to "high interrupt load") -- the old code re-enabled interrupts in the machine-specific hardware interrupt handler causing the handler to be re-entered, possible multiple times. Could lead to kernel stack overflows, and all sorts of mysterious crashes/hangs as a result. While here, fix up the IP32 interrupt handler code to also not re-enable interrupts. Thanks for ideas/comments go to Chuq and Stephen Ma.
