When an OA stream FD is open, removing the PCI device due to PCIe errors
or doing an unbind causes a NPD and system reboots. While OA registers a
fini handler with devm, the handler does not take into account active OA
connections.

Add code to quiesce OA connection on PCI remove/unbind.

v2: Sashiko Comments
v3: More Sashiko fixes and refactor
v4: More Sashiko fixes and refactor
v5: Drop unpinning of BO in quiesce (Sashiko)
