[dpdk-dev] [PATCH] eal_pci: Fix max_vfs missing for none igb_uio driver

[Michael Qiu <michael.qiu@intel.com>]

max_vfs will only be created by igb_uio driver, for other
drivers like vfio or pci_uio_generic, max_vfs will miss.

But sriov_numvfs is not driver related, just get the vf numbers
from that field.
