zebra: on local mac add from the dplane a re-install maybe need as static
As a part of extended MM handing a MAC can be updated from local
to remote while being referenced by SYNC neighs (this is really a
temporary/small window). During this window if the MAC transitions
back to local again we need to re-inforce the previous SYNC flags
(based on the sync-neigh count) as subsequent SYNC updates to the
MAC will be de-duped and ignored.
