Neels Hofmeyr 211169d794 bsc: handle RR Release messages 
Receive RR Release messages if they happen during lchan release. Add RR Release
to the alt{}s in both f_expect_chan_rel() to cover a whole bunch of test cases,
and in f_tc_ho_out_fail_no_ho_detect() which has its own release expectations.

Before this, RR Release messages would typically be lost in the RSL.clear
recently removed by Ie1be30c3f109dda8c58c523df508211f8e20aad3.

However, I still expect tests to pass after this, since the current osmo-bsc
master has a bug that omits RR Release messages (since [1]).

By applying this patch, both the buggy osmo-bsc (omitting RR Release) and the
fix of that [2] should pass the BSC tests. So far by accepting whatever comes
along, and not complaining if it doesn't come along.

A subsequent patch will more precisely ensure that exactly the expected
messages will be sent by osmo-bsc (Ibc64058f1e214bea585f4e8dcb66f3df8ead3845).
