Subject: [PATCH 11/16] virtio-scsi: clean up virtio_scsi_handle_event_vq()

RH-Author: Stefan Hajnoczi <stefanha@redhat.com>
RH-MergeRequest: 88: virtio-scsi: fix 100% CPU consumption with IOThreads
RH-Commit: [3/6] f8dbc4c1991c61e4cf8dea50942c3cd509c9c4bd (stefanha/centos-stream-qemu-kvm)
RH-Bugzilla: 2079347

virtio_scsi_handle_event_vq() is only called from hw/scsi/virtio-scsi.c
now and its return value is no longer used. Remove the function
prototype from virtio-scsi.h and drop the return value.
