Ensure we do not double-lock the same volume in create
When making containers, we want to lock all named volumes we are
adding the container to, to ensure they aren't removed from under
us while we are working. Unfortunately, this code did not account
for a container having the same volume mounted in multiple places
so it could deadlock. Add a map to ensure that we don't lock the
same name more than once to resolve this.
Fixes #8221
