NeilBrown 1ec22eb2b4 md: fix error path when duplicate name is found on md device creation. 
When an md device is created by name (rather than number) we need to
check that the name is not already in use.  If this check finds a
duplicate, we return an error without dropping the lock or freeing
the newly create mddev.
This patch fixes that.
