Turn NACK and GENI_TIMEOUT into debug prints to silence the kernel log
when running things such as i2cdetect to scan the bus.

As mentioned, I squashed it with the previous patch.

Additional note: the dbg messages in this function are superfluous. We
already have all this information with the tracepoints in i2c_transfer.
