Supply a valid Connect ID when issuing XPT_DEV_MATCH, which

Browse Source 
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.
