This, unless vector is already masked which unassigns irqfd already.
The logic in unassign was reversed, which left kvm irqfd assigned.
This patch is qemu-kvm only as irqfd is not upstream.

Hello,
In my testing of virtio-console, I found qemu-kvm.git introduces a lot
of overhead in thread scheduling compared to qemu.git.
My test sends a 260M file from the host to a guest via a virtio-console
port and then computes the sha1sum of the file on the host as well as on
the guest,
will be the first user.
