bareudp: Fix device stats updates.
Bareudp devices update their stats concurrently. Therefore they need proper atomic increments. Fixes: 571912c69f0e ("net: UDP tunnel encapsulation module for tunnelling different protocols like MPLS, IP, NSH etc.") Signed-off-by: Guillaume Nault <gnault@redhat.com> Reviewed-by: Willem de Bruijn <willemb@google.com> Link: https://patch.msgid.link/04b7b9d0b480158eb3ab4366ec80aa2ab7e41fcb.1725031794.git.gnault@redhat.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
