Kaushlendra Kumar b4bb16202d tools/power cpupower: Reset errno before strtoull() 
[ Upstream commit f9bd3762cf ]

cpuidle_state_get_one_value() never cleared errno before calling
strtoull(), so a prior ERANGE caused every cpuidle counter read to
return zero. Reset errno to 0 before the conversion so each sysfs read
is evaluated independently.
