Issue: In case of a Logical_Router without mac_binding_age_threshold set or a Logical_Router with an incorrectly formatted mac_binding_threshold option, entries were not being purged from the Mac Binding table in SouthBound.
This was because in the function `en_mac_binding_aging_run` in case of an invalid mac_binding_threshold entry or if mac_binding_threshold is not set we are returning from the loop instead of iterating through the remaining LRs. As a result, subsequent runs of the aging_waker node are also not scehduled and we end up not purging any MAC Bindings. Fix: This patch fixes this issue by changing the return to a continue so that we skip the current LR but continue processing for the remaining LRs. Fixes: 78851b6ffb58 ("northd: Support CIDR-based MAC binding aging threshold.")
