Subject: [PATCH v1 1/3] i40e: use minimal tx and rx pairs for kdump

Set the number of the MSI-X vectors to 1. When MSI-X is enabled, it's not allowed
to use more TC queue pairs than MSI-X vectors
(pf->num_lan_msix) exist. Thus the number of tx and rx pairs
(vsi->num_queue_pairs) will be equal to the number of MSI-X vectors, i.e., 1.
