mlxsw: spectrum_router: Propagate neighbour update errors

Browse Source 
Next patch will add offload indication to neighbours, but the indication
should only be altered in case the neighbour was successfully added to /
deleted from the device.

Propagate neighbour update errors, so that they could be taken into
account by the next patch.
