This, unless vector is already masked which unassigns irqfd already.
The logic in unassign was reversed, which left kvm irqfd assigned.

This patchset introduces support for assigning PCI devices to guests (kernel
part).
The main difference from the last version is reserving the PCI device for our
exclusive use so that multiple device assignment will fail, as will device
assignment when a driver for the device being assigned
This function injects an interrupt into the guest given the kvm struct,
