Change in osmo-bts[master]: l1sap: Avoid re-(de)activating already (de)active lchans

[pespin]

Hello Jenkins Builder, 

I'd like you to reexamine a change. Please visit

    https://gerrit.osmocom.org/c/osmo-bts/+/25965

l1sap: Avoid re-(de)activating already (de)active lchans

This avoids triggering all sorts of unexpected paths where one tries to
release an already released lchan, etc.
This can happen for instance if BTS shuts down due to BSC link going
down, and hence resets all lchans, announcing it to the PCU. Then the
PCU may try to deactivate the channel sending act_req (disable), but the
BTS already unilaterally dropped the channels.
That code path seems to trigger some crash, probably because something
in lchan has been freed.
