[PATCH] osmo-iuh[master]: rua: discard context maps on id-Disconnect

[Neels Hofmeyr]

Review at  https://gerrit.osmocom.org/5575

rua: discard context maps on id-Disconnect

When an id-Disconnect is received, the RUA to SCCP user context becomes unused.
Mark the context map as inactive in that case. It will be cleaned up by the
context map garbage collector.
