clang static analysis reports this error
amdgpu_smu.c:2289:9: warning: Called function pointer
  is null (null dereference)
        return smu->ppt_funcs->emit_clk_levels(
               ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

There is a logic error in the earlier check of
emit_clk_levels.  The error value is set to
the ret variable but ret is never used.  Return
directly and remove the unneeded ret variable.
