Fix example error_injection_tool

I got a "sched_setaffinity:: Invalid argument" error when using
err_injection_tool to inject error on a system with over 32 cpus.

Error information when injecting an error on a system with over 32 cpus:
$ ./err_injection_tool -i
/sys/devices/system/cpu/cpu0/err_inject//err_type_info

Configurations:
On cpu32: loop=10, interval=5(s) err_type_info=4101,err_struct_info=95
Error sched_setaffinity:: Invalid argument
All done

This because there is overflow when calculating the cpumask: the
type of (1<<k) is int, while mask[j] is unsigned long. When k > 31,
(1<<k) is truncated to ZERO, resulting in a unexpected cpumask.
