[PULL 25/25] virtio: drop unused virtio_device_stop_ioeventfd() function

[Michael S. Tsirkin]

From: Stefan Hajnoczi <address@hidden>

virtio_device_stop_ioeventfd() has not been used since commit
310837de6c1e0badfd736b1b316b1698c53120a7 ("virtio: introduce
grab/release_ioeventfd to fix vhost") in 2016.

Nowadays ioeventfd is stopped implicitly by the virtio transport when
lifecycle events such as the VM pausing or device unplug occur.
