The schednetisr() routine is supposed to be MP and interrupt safe, but wasn't
because it allocated its messages.  Instead of allocating a message use a
fixed message in the netisr structure.

Get rid of #ifdef SMP/#error.  DEVICE_POLLING now works on SMP builds.

Implement an emergency polling enable function to try to keep the system
operational in a degraded state if interrupt routing is blown.  NOTE: only
vr0 uses the feature at the moment, and DEVICE_POLLING must be enabled.
