Supply a valid Connect ID when issuing XPT_DEV_MATCH, which according to my reading of the CAM draft is mandatory for all CCB function calls and enforced by xptioctl() since at least r168752. Previously we happened to use 0 as the Path ID, causing the XPT_DEV_MATCH call to fail if there's no SCSI bus 0. Basically the same bug was also fixed the same way for camcontrol(8) as part of r126514.
