Subject: [PATCH] conncheck: nominate only one matching pair
This patch fixes a bug in priv_mark_pair_nominated(), where the local
candidate was not passed to the function, so removing the possibility to
find which local candidate the check was sent to.
Reviewed-by: Philip Withnall <philip@tecnocode.co.uk>
Differential Revision: https://phabricator.freedesktop.org/D808
(cherry picked from commit c309905ff446bed2dc47811023b98bc586a02d63)
