fs: Fix renameMu lock recursion.
dirent.walk() takes renameMu, but is often called with renameMu already held,
which can lead to a deadlock.
Fix this by requiring renameMu to be held for reading when dirent.walk() is
called. This causes walks and existence checks to block while a rename
operation takes place, but that is what we were already trying to enforce by
taking renameMu in walk() anyways.
