Klaus Jensen 83d7ed5c57 hw/nvme: fix pin-based interrupt behavior (again) ... Jakub noticed[1] that, when using pin-based interrupts, the device will unconditionally deasssert when any CQEs are acknowledged. However, the pin should not be deasserted if other completion queues still holds unacknowledged CQEs. The bug is an artifact of commit ca247d3509 ("hw/block/nvme: fix pin-based interrupt behavior") which fixed one bug but introduced another. This is the third time someone tries to fix pin-based interrupts (see commit 5e9aa92eb1 ("hw/block: Fix pin-based interrupt behaviour of NVMe"))... Third time's the charm, so fix it, again, by keeping track of how many CQs have unacknowledged CQEs and only deassert when all are cleared.
