    Do not remove router from dvr_snat agents on dvr port deletion

    When dvr serviceable port is deleted/migrated, dvr callback checks
    if there are any more dvr serviceable ports on the host and if
    there are no - removes the router from the agent on that host.
    To prevent snat namespace removal we need to check SNAT bindings
    and not remove router from l3 agent hosting SNAT.
