netfilter: reduce sparse warnings
bridge/netfilter/ebtables.c:290:26: warning: incorrect type in assignment (different modifiers) -> remove __pure annotation. ipv6/netfilter/ip6t_SYNPROXY.c:240:27: warning: cast from restricted __be16 -> switch ntohs to htons and vice versa. netfilter/core.c:391:30: warning: symbol 'nfq_ct_nat_hook' was not declared. Should it be static? -> delete it, got removed net/netfilter/nf_synproxy_core.c:221:48: warning: cast to restricted __be32 -> Use __be32 instead of u32. Tested with objdiff that these changes do not affect generated code. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
