xen/pv-on-hvm kexec: rebind virqs to existing eventchannel ports
During a kexec boot some virqs such as timer and debugirq were already
registered by the old kernel. The hypervisor will return -EEXISTS from
the new EVTCHNOP_bind_virq request and the BUG in bind_virq_to_irq()
triggers. Catch the -EEXISTS error and loop through all possible ports to find
what port belongs to the virq/cpu combo.

[v2:
- use NR_EVENT_CHANNELS instead of private MAX_EVTCHNS]
