ethdev: make TM shaper parameters constant

The function to add a new shaper profile in rte_tm should not (and does not) modify the profile parameters passed in via struct pointer. We should guarantee this by marking the parameter pointer as const. This allows SW to create multiple profiles using the same parameter struct without having to reset it each time.
