Subject: [PATCH net-next] liquidio: set sriov_totalvfs correctly

From: Derek Chickles <derek.chickles@...ium.com>

The file /sys/devices/pci000.../sriov_totalvfs is showing a wrong value.
Fix it by calling pci_sriov_set_totalvfs() to set the total number of VFs
available after calculations for the number of PF and VF queues are made.
