commit 9e36dca82aa139f10e25ca037cf4a7cc03eafea0

    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.
