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.
