Subject: [PATCH 5.10 492/717] vhost scsi: fix error return code in vhost_scsi_set_endpoint()

From: Zhang Changzhong <zhangchangzhong@...wei.com>

[ Upstream commit 2e1139d613c7fb0956e82f72a8281c0a475ad4f8 ]

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 25b98b64e284 ("vhost scsi: alloc cmds per vq instead of session")
