net/mlx5e: Use channel mdev reference instead of global mdev instance for coalescing

Browse source 
Channels can potentially have independent mdev instances. Do not refer to
the global mdev instance in the mlx5e_priv instance for channel FW
operations related to coalescing. CQ numbers that would be valid on the
channel's mdev instance may not be correctly referenced if using the
mlx5e_priv instance.
