detectGeneralBurst(): Increase log level about clipping to INFO

There's another related logging line also at INFO level in the caller
path in  Transceiver.cpp, but it only prints if detectBurst() failed.
Let's print this one as INFO too, which proved to be a good logging
level. This way user also notices gain is too high despite osmo-trx is
still able to decode bursts.
