Subject: use miss check, lead to null pointer crash

Hi lkrg team:
     In function p_ed_enforce_pcfi(),fellow code  miss check before use :
      p_frame.fp = *(unsigned long *)(p_fp - 12);
      p_frame.sp = *(unsigned long *)(p_fp - 8);
      p_frame.pc = *(unsigned long *)(p_fp - 4);
    above code will lead to null pointer crash.  This null pointer situation  exist LKRG complie by clang 8.0.
