netfilter: nft_flow_offload: fix underflow in flowtable reference counter
The .deactivate and .activate interfaces already deal with the reference counter. Otherwise, this results in spurious "Device is busy" errors. Fixes: a3c90f7a2323 ("netfilter: nf_tables: flow offload expression") Signed-off-by: wenxu <wenxu@ucloud.cn> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
