From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx> The SGL memory allocated during vhost_scsi_map_iov_to_sgl() setup was never getting freed during tv_cmd completion -> release path. Fix this up by releasing tv_cmd->tvc_sgl in vhost_scsi_free_cmd() ahead of tv_cmd descriptor free. Cc: Stefan Hajnoczi <stefanha@xxxxxxxxxxxxxxxxxx> Cc: Zhi Yong Wu <wuzhy@xxxxxxxxxx> Cc: Michael S.
