msc: Add net back pointer to gsm_trans 

Currently the net pointer is obtained from trans->subscr->net. On the
other hand, the list gsm_trans object is managed by the net object.

This patch adds the back pointer to the structure and replaces all
trans->subscr->net by trans->net expressions. In trans_alloc() the
trans->net pointer is obtained from the subscr object.
