ixgbe claims it supports 64 VFs in its SRIOV capability
 structure, but the driver only supports 63.  Adjust it
 so sysfs sriov configuration checking will check with
 the proper totalvf value.

Note: This is part of a 4-part patch set that demonstrates
      how a PF driver can enable its VF devices via sysfs.
      The final patch will be submitted by Intel via
      the linux-net mailing list.
