    sysmobts: Compatibility with older firmware versions
    
    When using a firmware version < 3.6, the call to l1if_mute_rf()
    returned an error, which caused an OML CHG ADM STATE NACK.
    
    Let's check if the l1if_mute_rf() call is an un-mute for all
    timeslots (which apparently we do always at start-up).  If it is, then
    acknowledge it even if muting is not supported by earlier firmwares.
    
    I suppose the change causing this problem was introduced in:
            commit b26b8fc77692e851469f3e27b9aeaeff233ffd2e
            Author: Holger Hans Peter Freyther <zecke at selfish.org>
            Date:   Tue Mar 4 15:03:59 2014 +0100
            sysmobts: Do a RF mute at initialization when the RC is locked
    
    With the current change applied, we can run the BTS with earlier
    firmware versions than 3.6.0 again.  Tested with 3.1 and 2.4
