[patch net-next] net: microchip: sparx5: remove useless code in sparx5_qos_init()

[Lu Wei]

There is no need to define variable ret, so remove it
and return sparx5_leak_groups_init() directly.

Does sparx5_qos_init() even make sense given that all it does it call
a function?

Please don't do the minimum needed to make your robot happy. Think
about the code, the change, is this the best fix?

sparx5_qos_init() will be expanded in later patch series, as new QoS
features require new initializations - so this is actually somewhat
intentional.

When do you expect such patches to land?

If it going to be soon, we can keep the code as it is. If it is going
to be a while, the bots are going to keep finding this and what to
remove it.

Most likely sometime in the next window.

I see. If bots will be bugging us regularly, then it might just be best
to let the patch through.
