netfilter: use forward declaration instead of including linux/proc_fs.h

We don't need to pull the full definitions in that file, a simple forward declaration is enough. Moreover, include linux/procfs.h from nf_synproxy_core, otherwise this hits a compilation error due to missing declarations, ie. net/netfilter/nf_synproxy_core.c: In function ‘synproxy_proc_init’: net/netfilter/nf_synproxy_core.c:326:2: error: implicit declaration of function ‘proc_create’ [-Werror=implicit-function-declaration] if (!proc_create("synproxy", S_IRUGO, net->proc_net_stat, ^ Signed-off-by: Pablo Neira Ayuso <[email protected]> Signed-off-by: Eric W.
