Subject: [PATCH iwl v2] i40e: print correct hw max rss count in kernel ring buffer

pf->rss_size_max is hardcoded and always prints max rss count as 64.

Eg:
  kernel: i40e 0000:af:00.1: User requested queue count/HW max RSS count:  104/64

whereas  ethtool reports the correct value from "vsi->num_queue_pairs"

Channel parameters for eno33:
Pre-set maximums:
RX:     n/a
TX:     n/a
Other:      1
Combined:   104
Current hardware settings:
RX:     n/a
TX:     n/a
Other:      1
Combined:   104  <-------

and is misleading.

Change it to vsi->num_queue_pairs
