Merge branch 'mV88e6xxx-interrupt-fixes'

Andrew Lunn says:

====================
Fixes for the MV88e6xxx interrupt code

The interrupt code was never tested with a board who's probing
resulted in an -EPROBE_DEFFERED. So the clean up paths never got
tested. I now do have -EPROBE_DEFFERED, and things break badly during
cleanup. These are the fixes.

This is fixing code in net-next.

v2:
Fix typo pointed out by David Miller
