====================
mlxsw: cleanup neigh handling

Ido says:

This series addresses long standing issues in the mlxsw driver
concerning neighbour reflection. It also prepares the code for follow-up
changes dealing with proper resource cleanup and nexthop reflection.

The first two patches convert the neighbour reflection code to use an
ordered workqueue, to prevent re-ordering of NEIGH_UPDATE events that
may happen following subsequent patches.

The third to fifth patches remove the ndo_neigh_{construct,destroy}
entry points from the driver, thereby relying only on NEIGH_UPDATE
events for neighbour reflection. This simplifies the code considerably.

Last patches are fallout and adjust nits in the code I noticed while
going over it.
