    l3 ha: don't send routers without '_ha_interface'

    Change I22ff5a5a74527366da8f82982232d4e70e455570 changed
    get_ha_sync_data_for_host such that if an agent requests a router's
    details, then it is always returned, even when it doesn't have the key
    '_ha_interface'. Further changes to this change tried to put this check
    back in (Ie38baf061d678fc5d768195b25241efbad74e42f), but this patch
    failed to do so for the case where no bindings were returned (possible
    when the router has been concurrently deleted). This patch puts this
    check back in.
