apparmor: fix an error code in __aa_create_ns()
We should return error pointers in this function. Returning NULL results in a NULL dereference in the caller. Fixes: 73688d1ed0b8 ("apparmor: refactor prepare_ns() and make usable from different views") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: John Johansen <john.johansen@canonical.com>
