sgsn: Fix access to subscr in sgsn_auth_update (Coverity)

Currently the access to subscr->sgsn_data->error_cause is not
protected against subscr == NULL like it is done in other code paths
of sgsn_auth_update.

This commit adds a conditional to avoid a NULL-dereference.

Fixes: Coverity CID 1264589
