net/mlx5e: Fix access to non-existing receive queue

In case number of channels is changed while interface is down,
RSS indirection table is mistakenly not modified accordingly,
causing access to out-of-range non-existing object.

Fix by updating the RSS indireciton table also in the early
return flow of interface down.

Fixes: fb35c534b788 ("net/mlx5e: Fix NULL pointer derefernce in set channels error flow")
Fixes: bbeb53b8b2c9 ("net/mlx5e: Move RSS params to a dedicated struct")
