net/mlx5: Replace global mlx5_intf_lock with HCA devcom component lock
mlx5_intf_lock is used to sync between LAG changes and its slaves
mlx5 core dev aux devices changes, which means every time mlx5 core
dev add/remove aux devices, mlx5 is taking this global lock, even if
LAG functionality isn't supported over the core dev.
This cause a bottleneck when probing VFs/SFs in parallel.
Hence, replace mlx5_intf_lock with HCA devcom component lock, or no
lock if LAG functionality isn't supported.
