Issue 4293/3: smobs.tcc: robustify {mark,print}_trampoline in connection with free_smob

Guilev2 has little qualms calling mark/print even after freeing a smob.
So we clean out the pointer to smob data when freeing/unregistering it,
and let the mark/print trampolines detect this condition and punt.
