Kurt Kanzenbach 07adb69545 timekeeping: Mark NMI safe time accessors as notrace 
commit 2c33d775ef upstream.

Mark the CLOCK_MONOTONIC fast time accessors as notrace. These functions are
used in tracing to retrieve timestamps, so they should not recurse.

Fixes: 4498e7467e ("time: Parametrize all tk_fast_mono users")
Fixes: f09cb9a180 ("time: Introduce tk_fast_raw")
