## Summary
Fix three issues found while reviewing the clock and CPU-load paths:
Keep the RTC synchronized when CLOCK_REALTIME is changed with
CONFIG_CLOCK_TIMEKEEPING=y. The existing RTC update path is now shared by both
timekeeping and non-timekeeping configurations, including the LPWORK path for
RTC drivers that may block.
Validate the PID hash entry before updating critical-monitor CPU-load
data. This prevents an invalid or stale PID from passing a NULL TCB to
nxsched_update_critmon() and keeps the TCB stable under the existing scheduler
critical section.
Normalize CLOCK_FD failures from clock_getres(). Errors from PTP clock
lookup and PTP_CLOCK_GETRES now return ERROR and set errno, matching the public
API convention used by the other clock_getres() paths.
