[v2,0/2] PCI/IOV: sriov_numvfs bug fixes

Message

A deadlock condition was discovered by SPDK when removing an SRIOV-enabled and
VFIO-attached device, with a specific threading model. While discussing this
on the mailing list, a separate issue around updating sriov_numvfs and its
kobject_uevent() was also discovered. This series fixes both of those issues.

---
v1 => v2:
* No code changes
* Updated commit messages per feedback from Bjorn
* Added Leon's Reviewed-by tags
* Moved bulk of the v1 cover letter to the revert patch commit message where
  it belonged
