Bruce Evans 94ca32a3f5 Don't switch from fast interrupt handlers to normal interrupt
handlers if interrupts are nested more than a few (3) deep.  This
only reduces the maximum nesting level by 1 with the standard
drivers unless there is a related bug somewhere, but can't hurt
much (the worst case is returning to hoggish interrupt handler like
wdintr(), but such interrupt handlers hurt anyway).

Fixed a previously harmless race incrementing the interrupt nesting
level.

This should be in 2.1.6 and 2.2.
