No, this makes things worse - we should acquire resources in the device
level probe so that we handle deferred probe more gracefully, triggering
a defer from the device trying to acquire the resource makes it clearer
what's going on and reduces the amount of work we do on deferred probe
attempts.  Having an interrupt registered has no meaningful cost.
