fix: mdadm -Ss for external metadata don't stop container

Sometimes (~50%) mdadm -Ss cannot stop container as mdmon opens its device
and do not close it before exit(). The period between open and release of
handle is too long and md is not able stop device. Releasing handle before
exit does not block md.
