ceph: mark directory as non-complete after loading key
When setting a directory's crypt context, ceph_dir_clear_complete()
needs to be called otherwise if it was complete before, any existing
(old) dentry will still be valid.
This patch adds a wrapper around __fscrypt_prepare_readdir() which will
ensure a directory is marked as non-complete if key status changes.
