net/mlx5: Lag, restore buckets number to default after hash LAG deactivation

Browse Source 
The cited patch introduces the concept of buckets in LAG in hash mode.
However, the patch doesn't clear the number of buckets in the LAG
deactivation. This results in using the wrong number of buckets in
case user create a hash mode LAG and afterwards create a non-hash
mode LAG.

Hence, restore buckets number to default after hash mode LAG
deactivation.
