tracing: Drop unused helper function to fix the build

Browse Source 
A helper function defined but not used. This, in particular,
prevents kernel builds with clang, `make W=1` and CONFIG_WERROR=y:

kernel/trace/trace.c:2229:19: error: unused function 'run_tracer_selftest' [-Werror,-Wunused-function]
 2229 | static inline int run_tracer_selftest(struct tracer *type)
      |                   ^~~~~~~~~~~~~~~~~~~

Fix this by dropping unused functions.

See also commit 6863f5643d ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
