Eric Biggers 08d5c8445d ext4: disable fast-commit of encrypted dir operations
commit 0fbcb5251fc81b58969b272c4fb7374a7b922e3e upstream.

fast-commit of create, link, and unlink operations in encrypted
directories is completely broken because the unencrypted filenames are
being written to the fast-commit journal instead of the encrypted
filenames.  These operations can't be replayed, as encryption keys
aren't present at journal replay time.  It is also an information leak.

Until if/when we can get this working properly, make encrypted directory
operations ineligible for fast-commit.

Note that fast-commit operations on encrypted regular files continue to
be allowed, as they seem to work.

Fixes: aa75f4d3da ("ext4: main fast-commit commit path")
