description:
Back out previous KASSERTMSG for now.

The immediate problem appears to have been elsewhere, in the wrong
interrupt level passed by the Xen-specific intr_establish to
event_set_handler.

We should maybe restore these assertions later, but at least one was
violated before cherry's interrupt rototill anyway.
