Log Message:
Some devices (e.g. ixg in MSI-X mode) don't to have their handlers called
when no interrupt are pending. So add an extra ih_pending field
to struct intrhand, which is incremeted when the handler is not called because
of IPL level and reset to 0 when called. Check this in Xen's resume
assembly to call only handlers that are really pending.
