Subject: [PATCH] vhost-vdpa: Fix the wrong input in config_cb
Git-commit: bcef9356fc2e1302daf373c83c826aa27954d128
Patch-mainline: v5.15-rc6
References: stable-5.14.14

commit bcef9356fc2e1302daf373c83c826aa27954d128 upstream.

Fix the wrong input in for config_cb. In function vhost_vdpa_config_cb,
the input cb.private was used as struct vhost_vdpa, so the input was
wrong here, fix this issue
