mlxsw: Convert does-RIF-have-this-netdev queries to a dedicated helper
In a number of places, a netdevice underlying a RIF is obtained only to
compare it to another pointer. In order to clean up the interface between
the router and the other modules, add a new helper to specifically answer
this question, and convert the relevant uses to this new interface.
