x86: Make tsc=reliable override boot time stability checks

This patch makes the tsc=reliable option disable the boot time
stability checks. Currently the option only disables the runtime
watchdog checks. This change allows folks who want to override the
boot time TSC stability checks and use the TSC when the system would
otherwise disqualify it.

There still are some situations that the TSC will be disqualified,
such as cpufreq scaling. But these are situations where the box will
hang if allowed.

Patch also includes a fix for an issue found by Thomas Gleixner, where
the TSC disqualification message wouldn't be printed after a call to
unsynchronized_tsc().
