crosperf: Add check core online in PinGovernerFrequency().

Due to Hyper-Threading is disabled, not all cpus in
/sys/devices/system/cpu/cpu* are online on the x86 DUTs. Our
PinGovernerFrequency() functions need to write performance to
scaling_governor and it fails if the cpu is offline. This patches
adds checks before writing to make sure the core is not offline.

BUG=None
TEST=Local tests.
