linux-next: manual merge of the vhost tree with the target-updates tree

Hi Michael,

Today's linux-next merge of the vhost tree got a conflict in
drivers/vhost/scsi.c between commit 084ed45b3846 ("vhost/scsi: Convert to
se_cmd->cmd_kref TARGET_SCF_ACK_KREF usage") from the target-updates tree
and commit 3c63f66a0dcd ("vhost-scsi: Rename struct tcm_vhost_cmd *tv_cmd
to *cmd") from the vhost tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
