Subject: [PATCH] src: chain: Add missing nftnl_chain_rule_del()

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1666495
Upstream Status: libnftnl commit de5a23d26828a

commit de5a23d26828a1e1f2d3351b0414925857546496
Author: Phil Sutter <phil@nwl.cc>

    src: chain: Add missing nftnl_chain_rule_del()

    Although identical to nftnl_rule_list_del(), this function adheres to
    the common naming style of per chain rule list routines introduced
    earlier, therefore helps with deprecating the global rule list API at a
    later point.

    Fixes: e33798478176f ("chain: Support per chain rules list")
