Peter Hilber 7cec7d8388 timekeeping: Fix cross-timestamp interpolation on counter wrap
[ Upstream commit 84dccadd3e2a3f1a373826ad71e5ced5e76b0c00 ]

cycle_between() decides whether get_device_system_crosststamp() will
interpolate for older counter readings.

cycle_between() yields wrong results for a counter wrap-around where after
< before < test, and for the case after < test < before.

Fix the comparison logic.

Fixes: 2c756feb18 ("time: Add history to cross timestamp interface supporting slower devices")
