Fix the value comparisons in the IDLETIME wakeup handler.

LessThan/GreaterThan comparisons were used in the wakeup handler,
and LessOrEqual/GreaterOrEqual in the block handler.

Change it to use LessOrEqual/GreaterOrEqual in both functions,
since this is what XSyncNegativeComparison and
XSyncPositiveComparison imply.
