When CONFIG_MODULES is disabled, clang warns:
kernel/trace/trace_events.c:872:5: warning: 'CONFIG_MODULES' is not defined, evaluates to 0 [-Wundef]
872 | #if CONFIG_MODULES
| ^
Use '#ifdef' to resolve the warning.
Fixes: b355247df104 ("tracing: Cache ":mod:" events for modules not loaded yet")
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202501190121.E2CIJuUj-lkp@intel.com/

Yes yes, I had this fixed locally but never tested nor pushed it out. :-p
