sgsn/test: Fix memory leak in test_subscriber_gsup

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.

Addresses:
== 372 bytes in 1 blocks are possibly lost in loss record 7 of 9
==    at 0x402A17C: malloc (in /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so)
==    by 0x4059FB8: _talloc_zero (talloc.c:354)
==    by 0x8055B82: sgsn_mm_ctx_alloc (gprs_sgsn.c:167)
==    by 0x804A336: alloc_mm_ctx (sgsn_test.c:140)
==    by 0x804B24D: test_subscriber_gsup (sgsn_test.c:503)
==    by 0x804EC99: main (sgsn_test.c:1853)
