<div class='commit-subject'>netfilter: conntrack: simplify the code by using nf_conntrack_get_ht</div><div class='commit-msg'>Since commit 64b87639c9cb ("netfilter: conntrack: fix race between
nf_conntrack proc read and hash resize") introduce the
nf_conntrack_get_ht, so there's no need to check nf_conntrack_generation
again and again to get the hash table and hash size. And convert
nf_conntrack_get_ht to inline function here.
