[PATCH] kernel: time: Return ENXIO instead of ENODEV when call smp_call_function_single fail in clockevents_unbind

[gchen]

From: Chen Gang <gchen@xxxxxxxxxxxxxxx>

smp_call_function_single will return -ENXIO for failure, so ENXIO needs
to be as the default value of cu.res for return instead of ENODEV.
