i40e: validate ring_len parameter against hardware-specific values

The maximum number of descriptors supported by the hardware is
hardware-dependent and can be retrieved using
i40e_get_max_num_descriptors(). Move this function to a shared header
and use it when checking for valid ring_len parameter rather than using
hardcoded value.

By fixing an over-acceptance issue, behavior change could be seen where
ring_len could now be rejected while configuring rx and tx queues if its
size is larger than the hardware-dependent maximum number of
descriptors.
