sata_nv: add back some verbosity into ADMA error_handler
Some debug output in the ADMA error_handler function was removed recently,
but it may be useful in certain cases, like NCQ commands timing out. Add it
back in, but make it a bit more intelligent so that it only prints if
command(s) are active and only prints the CPBs for those commands.
That way it won't spew at inappropriate times like suspend/resume.
