ceph: set DCACHE_NOKEY_NAME flag in ceph_lookup/atomic_open()

This is required so that we know to invalidate these dentries when the
directory is unlocked.

Atomic open can act as a lookup if handed a dentry that is negative on
the MDS. Ensure that we set DCACHE_NOKEY_NAME on the dentry in
atomic_open, if we don't have the key for the parent. Otherwise, we can
end up validating the dentry inappropriately if someone later adds a
key.
