time/jiffies: Mark jiffies_64_to_clock_t() notrace

Browse Source 
The trace_clock_jiffies() function that handles the "uptime" clock for
tracing calls jiffies_64_to_clock_t(). This causes the function tracer to
constantly recurse when the tracing clock is set to "uptime". Mark it
notrace to prevent unnecessary recursion when using the "uptime" clock.

Fixes: 58d4e21e50 ("tracing: Fix wraparound problems in "uptime" trace clock")
