netfilter: log: netns NULL ptr bug when calling from conntrack
Since (69b34fb netfilter: xt_LOG: add net namespace support
for xt_LOG), we hit this:
[ 4224.708977] BUG: unable to handle kernel NULL pointer dereference at 0000000000000388
[ 4224.709074] IP: [<ffffffff8147f699>] ipt_log_packet+0x29/0x270
when callling log functions from conntrack both in and out
are NULL i.e. the net pointer is invalid.
Adding struct net *net in call to nf_logfn() will secure that
there always is a vaild net ptr.
