Mitch Williams 9e5634dfb4 i40e: Don't disable SR-IOV when VFs are assigned 
When VFs are assigned to active VMs and we disable SR-IOV out from under them,
bad things happen. Currently, the VM does not crash, but the VFs lose all
resources and have no way to get them back.

Add an additional check for when the user is disabling through sysfs, and add a
comment to clarify why we check twice.
