1. cet/shstk_alloc.c: will not show content of switched ssp due to kerne… …

   …l improvement
   
   Since the v6.5 cycle latest cet userspace shstk patch improvements, switched
   ssp content will be protected and it makes sense, if code wants to show the
   switched ssp content, it will get fake segfault like this:
   "
   ssp0 & (-8): 7f5d4efffff8
   Segmentation fault (core dumped)
   "
   Dmesg shows the segfault as following:
   "
   shstk_alloc[3080]: segfault at 7f5d4e7ff000 ip 0000000000401258 sp 00007ffcd214f180 error 4 in shstk_alloc[401000+1000] likely on CPU 15 (core 3, socket 0)
   "
   So code should not show worked and switched ssp content to avoid fake failure.
