vhost-scsi: create a vhost-scsi-common abstraction
In order to introduce a new vhost-user-scsi host device type, it makes sense to abstract part of vhost-scsi into a common parent class. This commit does exactly that. Signed-off-by: Felipe Franciosi <felipe@nutanix.com> Message-Id: <1488479153-21203-3-git-send-email-felipe@nutanix.com>
