Merge remote-tracking branch 'remotes/bonzini/scsi-next' into staging

* remotes/bonzini/scsi-next:
  megasas: remove buildtime strings
  block: iscsi build fix if LIBISCSI_FEATURE_IOVECTOR is not defined
  virtio-scsi: Plug memory leak on virtio_scsi_push_event() error path
  scsi: Document intentional fall through in scsi_req_length()
