David Woodhouse 4ea9439fd5 KVM: x86/xen: Validate port number in SCHEDOP_poll 
We shouldn't allow guests to poll on arbitrary port numbers off the end
of the event channel table.

Fixes: 1a65105a5a ("KVM: x86/xen: handle PV spinlocks slowpath")
[dwmw2: my bug though; the original version did check the validity as a
 side-effect of an idr_find() which I ripped out in refactoring.]
