Reset switchtime to zero rather than the current CPU ticker (TSC) value.

Browse Source 
It is more appropriate in this context because TSC MSR is reset to zero
when the CPU is restarted from S3 and above.  Move acpi_resync_clock() back
to where it was before r211202.  It does not make a difference any more.
