net/mlx5e: Properly set default values when disabling adaptive moderation

Browse Source 
Add a call to mlx5e_reset_rx/tx_moderation() when enabling/disabling
adaptive moderation, in order to select the proper default values.

In order to do so, we separate the logic of selecting the moderation values
and setting moderion mode (CQE/EQE based).

Fixes: 0088cbbc4b ("net/mlx5e: Enable CQE based moderation on TX CQ")
Fixes: 9908aa2929 ("net/mlx5e: CQE based moderation")
