netfilter: x_tables: fix match/target revision lookup
Upstream commit 656caff: Commit 55b69e91 (netfilter: implement NFPROTO_UNSPEC as a wildcard for extensions) broke revision probing for matches and targets that are registered with NFPROTO_UNSPEC. Fix by continuing the search on the NFPROTO_UNSPEC list if nothing is found on the af-specific lists. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
