    PCI: SR-IOV quirk for Intel 82576 NIC

    If BIOS doesn't allocate resources for the SR-IOV BARs, zero the Flash
    BAR and program the SR-IOV BARs to use the old Flash Memory Space.

    Please refer to Intel 82576 Gigabit Ethernet Controller Datasheet
    section 7.9.2.14.2 for details.

This quirk was added before SR-IOV was in production and now all machines that
originally had this issue alreayd have bios updates to correct the issue. The
quirk itself is no longer needed and in fact causes bugs if run.  Remove it.
