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.
