More tracing fixes for 6.11:

- Move declaration of interface_lock outside of CONFIG_TIMERLAT_TRACER
 
   The fix to some locking races moved the declaration of the
   interface_lock up in the file, but also moved it into the
   CONFIG_TIMERLAT_TRACER #ifdef block, breaking the build when
   that wasn't set. Move it further up and out of that #ifdef block.
 
 - Remove unused function run_tracer_selftest() stub
 
   When CONFIG_FTRACE_STARTUP_TEST is not set the stub function
   run_tracer_selftest() is not used and clang is warning about it.
   Remove the function stub as it is not needed.
