udf: Protect rename against modification of moved directory
When we are renaming a directory to a different directory, we need to
update '..' entry in the moved directory. However nothing prevents moved
directory from being modified and even converted from the in-ICB format
to the normal format which results in a crash. Fix the problem by
locking the moved directory.
