[PATCH] md: Clear clevel whenever level is set.
The 'level' of an md array can be set as either a number of a string. When one is set, the other must be marked 'undefined'. This wasn't being done in one place: where new arrays are created. Result: if md1 is a raid1, it is stopped and a raid5 is created there, it might still appear to be a raid1.
