Subject: [PATCH] ceph: fix memory leak in mount error path when using test_dummy_encryption
Because ceph_init_fs_context() will never be invoced in case we get a
mount error, destroy_mount_options() won't be releasing fscrypt resources
with fscrypt_free_dummy_policy(). This will result in a memory leak. Add
an invocation to this function in the mount error path.
