Fix "--remove faulty" and similar commands.
A recent change to improve error messages for subdev management broken all use cases were device names like %d:%d were used. Re-arrange the code again so we use dev_open first - which understands those names - and then only try 'stat' if that failed. The important thing is to base the 'Cannot find' message on the result of 'stat', not on the result of 'open'. Signed-off-by: NeilBrown <neilb@suse.de>
