[PATCH] Calling check_system_tsc_reliable before unsynchronized_tsc

[Zhenzhong Duan]

unsynchronized_tsc() checks value of tsc_clocksource_reliable which is set by
check_system_tsc_reliable(). It's better to move check_system_tsc_reliable() at
front, or else this check makes no sense.

Though X86_FEATURE_CONSTANT_TSC is usually set for TSC reliable system, just in
case.
