Uros BizjakandGreg Kroah-Hartman dd72b3ac2f tracing: Use atomic64_inc_return() in trace_clock_counter() ...

[ Upstream commit eb887c4567 ]

Use atomic64_inc_return(&ref) instead of atomic64_add_return(1, &ref)
to use optimized implementation and ease register pressure around
the primitive for targets that implement optimized variant.
