fix: send RR Release (e.g. after BSSMAP Clear Cmd)
After commit [1], the code makes sure to disassociate lchan and conn before
invoking the lchan release. However, we only send RR Release if a conn is
present, which clearly is nonsense after [1].
[1] commit 8b818a01b00ea3daad4ad58c162ac52b4f08a5cb
"subscr conn: properly forget lchan before release"
Change-Id: I4fd582b41ba4599af704d670af83651d2450b1db
Manage sending of RR Release via a flag, set during invoking lchan release.
Add do_rr_release arg to lchan_release(), gscon_release_lchans(). In
lchan_fsm.c, send RR Release only if do_rr_release was passed true; do not care
whether a conn is still associated (because it won't ever be since [1]).
That way we can intelligently decide what release process makes sense (whether
the lchan terminates the subscriber connection or whether the connection goes
on at another lchan), and still disassociate lchan and conn early.
BTW, this problem wasn't caught by the stock OsmoBSC TTCN3 tests, because the
f_expect_chan_rel() don't care whether an RR Release happens or not. This is
being fixed by Ibc64058f1e214bea585f4e8dcb66f3df8ead3845.
So far this patch should fix BSC_Tests_LCLS.TC_lcls_connect_clear.
