[PATCH] Fix getdelays.c - cpumask length and error reporting
Fix the length passed while (un)registering cpumask. We were passing sizeof the array, make it strlen(). Error value printed in fatal errors should be derived from the message. The message contains an nlmsgerr embedded with an error value. We must report that value to the user.
