Log use of incompatible BS-AG-BLKS-RES value 

There's "channel-descrption bs-ag-blks-res" vty command which sets
BS-AG-BLKS-RES which might be too high if CCCH is combined with
SDCCHs. Previously proper value was silently enforced. Log this
situation explicitly and add spec reference to the comment.
