Change subject: l1ctl: do not explicitly decativate all lchans on L1CTL_DM_EST_REQ
......................................................................


Patch Set 1:

I think I only now understand where this is intent to go: To have multiple concurrently active dedicated channels in a single L1 instance.

Sorry, but I just think that's wrong.  A L1 is for a single MS/UE, and that has only a single dedicated channel at any given point in time (exception: HSCSD with channel bundling, whcih we don't aim to support).

If you have a use case where you need to simulate multiple MS, then there must be one virtual "layer 1 instance" per MS.  In osmo-bts-virtual, I implemented this by being able to accept multiple connections to the L1CTL unix domain socket, where eahc connection represents one virtual MS.

Not sure if the same is possibel in trxcon [yet]?
