[v2,0/5] qtest: pci and e1000e/igb msix fixes

Message

This series fixes some iomap balance issues and enables msix
sharing bar0, which will be required for some future XHCI
test cases.

It also removes the invalid write to msix PBA memory by
qtest, and fixes that properly by unmasking and taking
delivery of the msix interrupt in e1000e and igb tests, as
other test cases do.

Since v1:
- Patch 4 update comments as suggested by Akihiko Odaki.
- Patch 5 significantly rework and simplify also suggested
  by Akihiko Odaki. In particular the msi vectors are always
  unmasked to avoid the extra case of handling masked.

Thanks,
Nick
