Apply patch, requested by gson in ticket #981:
        sys/dev/ic/esiop.c                              1.57 via patch
Turn the "siop_intr: I shouldn't be there !" panic message in the
esiop driver into a printf followed by a return from the interrupt
handler.  The condition is triggered on some KVM virtual hosts,
apparently harmlessly, and not panicing makes it possible to boot a
NetBSD GENERIC kernel on those hosts. Fixes PR kern/48277.
