Allow ADAMLF to get the default dbid directly

Allow ADAMLF to get the default dbid directly from ADALNK for every command it issues. Currently a multi-fetch command does not go to the correct ADABAS nucleus because ADAMLF used the original default dbid in ADALNK where as we change ADALNK to dynamically to specify the default. Currently this is allowed with Special Purpose zap AY814045
