ieee1394: sbp2: remove irritating log message
The queue depth can be read from /sys/bus/scsi/devices/*/queue_depth, so don't log it. And the hint about speed improvements is misleading, at least under current kernels. If serialization is switched off, read performance is typically increased by less than 10%. (I did not test write performance recently.) On the other hand, serialize_io=0 is not yet safe due to some implementation issues that are not trivial to fix. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
