SGSN: Code to help debug / fix sgsn crash in cb_data_ind()

A crash was obsserved in cb_data_ind() when mm is dereferenced.

This patch adds some safeguards that try to prevent the library handle
back-pointer to the pdp_ctx to be NULL, and print a stack backtrace in
case we are free() ing the sgsn-side pdp_ctx while there's still a
library handle attached.
