UBUNTU: SAUCE: netfilter: xt_connlimit: remove the 'addr' parameter in add_hlist()

BugLink: https://bugs.launchpad.net/bugs/1811094

The previous commit made the 'addr' parameter in add_hlist() unused.  So remove it
with a SAUCE patch, to simplify the backport of the next patches, as it is removed
anyway in upstream later (but before the next patches) through commit 625c5561
("netfilter: connlimit: split xt_connlimit into front and backend"), in the rename
from 'xt_connlimit.c' to 'nf_conncount.c', which is a large refactor we don't need.
