Only return the current cpu if it's in the cpumask

Authored by andrew on Aug 10 2017, 5:08 PM.



When we restrict the cpumask it probably means we are unable to
sent interrupts to CPUs outside the map. As such only return the
current CPU when it's within the mask otherwise return the first
valid CPU.

This is needed on ThunderX as, in a dual socket configuration, we
are unable to send MSI/MSI-X interrupts between sockets.
