Currently the MM context is not deleted when a GSUP location
cancellation message is processed, because the real
sgsn_update_subscriber_data function has been wrapped to a dummy
implementation.
This commit adds an explicit call to sgsn_mm_ctx_cleanup_free which
also unassigns the LLME, so the call to gprs_llgmm_assign is removed.
It also adds an assertion to check that there are no talloc'ed blocks
left in tall_bsc_ctx.
