filter/nat: Fix the context for the imsi assignment

In c09f8a3b7fb94ccef41e33c32bfe2bff1ffe0e44 as part of a cleanup I accidently changed the talloc context from "con" to "bsc". The issue occurred at an earlier commit when assigning req.ctx to the "wrong" context. The allocation needs to be scoped by the struct nat_sccp_connection and not the connection from BSC to NAT.

Before we have a nat_sccp_connection we scope the copied imsi to the bsc_connection and then steal it, but for the identity resp we will always have a nat_sccp_connection and can already use the right context.
