dm mpath: fix stalls when handling invalid ioctls
An invalid ioctl will never be valid, irrespective of whether multipath has active paths or not. So for invalid ioctls we do not have to wait for multipath to activate any paths, but can rather return an error code immediately. This fix resolves numerous instances of: udevd[]: worker [] unexpectedly returned with status 0x0100 that have been seen during testing. Signed-off-by:Hannes Reinecke <hare@suse.de> Signed-off-by:
