Subject: [PATCH] PCI: Fix /sys warning when sriov enabled and card is hot
 removed

sysfs is a bit stricter now and emits warnings in more cases.

For SRIOV hotplug, we are calling pci_stop_dev() for each VF first
(after we update pci_stop_bus_devices) which remove each VF subdir.  So
double check the VF dir in /sys before trying to remove the physfn link.
