mlxsw: spectrum: Export function to check if RIF exists
After the previous patch, all the callers of mlxsw_sp_rif_find_by_dev()
outside of the routing code use it to understand if a RIF exists for the
passed netdev.
Therefore, export a function to check if a RIF exists and make
mlxsw_sp_rif_find_by_dev() internal to the routing code.
This will later allow us to more easily introduce the router lock which
will also protect the RIFs.
