hwclock: use carefully synchronize_to_clock_tick() return codes
* It seems that
rtc-isl1208 0-006f: chip found, driver version 0.3
rtc-isl1208 0-006f: rtc core: registered rtc-isl1208 as rtc0
rtc-isl1208 0-006f: rtc power failure detected, please set clock.
causes that hardware clock returns persistent time and synchronization
is impossible. The hwclock(8) has to ignore this problem and allows to
set clock anyway.
* synchronize_to_clock_tick() shouldn't to print the "...got clock tick"
debug message in case of failure.
