Subject: net/mlx5e: Do not reset Receive Queue params on every type change
Patch-mainline: v4.17-rc1
Git-commit: 2a0f561bf81c13d36910c7312ac8c67f83320a07
References: bsc#1046303 FATE#322944
Do not implicit a call to mlx5e_init_rq_type_params() upon every
change in RQ type. It should be called only on channels creation.
Fixes: 2fc4bfb7250d ("net/mlx5e: Dynamic RQ type infrastructure")
