btrfs: don't accept bare namespace as a valid xattr
commit 3c3b04d10ff1811a27f86684ccd2f5ba6983211d upstream.
Due to insufficient check in btrfs_is_valid_xattr, this unexpectedly
works:
$ touch file
$ setfattr -n user. -v 1 file
$ getfattr -d file
user.="1"
ie. the missing attribute name after the namespace.
