Juergen Gross 44a455e06d xen/events: fix race in evtchn_fifo_unmask() 
commit f013371974 upstream.

Unmasking a fifo event channel can result in unmasking it twice, once
directly in the kernel and once via a hypercall in case the event was
pending.

Fix that by doing the local unmask only if the event is not pending.

This is part of XSA-332.
