ceph: don't use -ESTALE as special return code in try_get_cap_refs
In some cases, we may want to return -ESTALE if it ends up that we're dealing with an inode that no longer exists. Switch to using -EUCLEAN as the "special" error return. Signed-off-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
