ecryptfs: show filename encryption options
ecryptfs_show_options() prints most user-visible mount options but
omits the filename encryption cipher and key size.
Print ecryptfs_fn_cipher and ecryptfs_fn_key_bytes when filename
encryption is enabled so that the displayed mount options reflect the
active filename encryption settings.
Fixes: 87c94c4df014 ("eCryptfs: Filename Encryption: mount option")
