wasp: drivers: nrf_rtc: Fix a nasty bug when setting the time

Browse source 
The code to recalculate the uptime to walltime adjustment was broken
(e.g. the longer we leave it after reboot the more inaccurate the time
setting becomes).

Fixes: 80079e4 ("wasp: nrf_rtc: Add a tiny bit of extra resolution")
