vhost-scsi: Include prot_bytes into expected data transfer length
This patch updates vhost_scsi_get_tag() to accept the combined expected data transfer length + T10 PI bytes as the value passed into target_submit_cmd(). This is required now that target-core logic in commit 14ef9200 expects to subtract se_cmd->prot_length from se_cmd->data_length. Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Michael S.
