Use correct upstream name for /dev/xen/evtchn.

This name has been upstream since forever and the typo here was leaving us with two device nodes.

If the device is not present then do not create it. The assumption that /dev/xen/ev{en,}tchn is minor 63 does not hold since the driver requests a dynamic minor.
