The queues assigned to a matrix mediated device are currently reset when:
- The VFIO_DEVICE_RESET ioctl is invoked
- The mdev fd is closed by userspace (QEMU)
- The mdev is removed from sysfs.
Immediately after the reset of a queue, a call is made to disable interrupts for the queue. This is entirely unnecessary because the reset of a queue disables interrupts, so this will be removed.
