fscrypt: remove fscrypt_fname_usr_to_disk()
fscrypt_fname_usr_to_disk() sounded very generic but was actually only used to encrypt symlinks. Remove it now that all filesystems have been switched over to fscrypt_encrypt_symlink(). Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
