igb: Check if subordinate VFs are assigned to virtual machines
Kvm and the Xen pci-back driver will set a flag in the virtual function
pci device dev_flags when the VF is assigned to a guest VM. Before
destroying subordinate VFs check to see if the flag is set and if so
skip the call to pci_disable_sriov() to avoid system crashes.
Copy the maintainer for the Xen pci-back driver. Also CC'ing
maintainers of all drivers found to call pci_disable_sriov().
