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.
