commit 9f722fb

In later patch, the mlx5_clock will be allocated dynamically, its
address can be obtained from mlx5_core_dev struct, but mdev can't be
obtained from mlx5_clock because it can be shared by multiple
interfaces. So change the parameter for such internal functions, only
mdev is passed down from the callers.
