Sometimes after failure in creation (exp. due to duplicate devices
in create command) newly created empty md array will not be stopped
due to openers>1 (create_mddev will not manage to drop lock).
In this case ioctl() will return error - this needs to be checked
and if occurs - sending STOP_ARRAY should be repeat after delay
to make sure that mddev is stopped correctly.
