quota: Fix WARN_ON in lookup_one_len
We should hold i_mutex when looking up quota files for journaled quotas, otherwise a WARN_ON in lookup_one_len triggers. The fact that we didn't hold i_mutex previously probably could not lead to a real bug since the filesystem is just being mounted / remounted read-write and thus the root directory cannot change anyway but it's definitely cleaner with i_mutex.
