trx: avoid deactivating lchan on LCHAN_REL_ACT_REACT
* do not deactivate lchan when called with LCHAN_REL_ACT_REACT
* add fixme comment
It's unclear yet if any special steps are required for osmo-bts-trx so
let's just make it compatible with setups [1] using BS_AG_BLKS_RES != 1
for now.
Background: CCCH is auto activated by some OsmoBTS - before we receive
SI3, see 4a8582846281322e8d7dfc577b18767cf35c24d1. To accommodate for
that we deactivate CCCH in common/rsl.c, which triggers BTS-model
specific callback sapi_deactivate_cb() which updates parameters and
activates it again.
In case of osmo-bts-trx there is no auto-activation and (seems to be) no
need in special interaction with hw to activate channel (no
lchan_activate()) hence we can just skip entire
deactivate/setup/activate again routine.
[1] "channel-descrption bs-ag-blks-res N" in OpenBSC config file.
