Now that CONFIG_HVM can (and should) be turned off for the shim, gcc 8.2
apparently is no longer sure that "port" is indeed initialized at
if ( sched_poll->nr_ports == 1 )
v->poll_evtchn = port;
It doesn't look to be impossible for the compiler to prove it is not,
but we also can't rely on that to be the case. Add an initializer.
