Put probe-time printf of adapter speed and duplex behind bootverbose:

since the link takes a bit to negotiate, the information is pretty
much never available during the probe.  As such, the boot output
pretty much always prints N/A for speed and duplex.  Since we print
out the output of ifconfig during the user space boot, this early
boot information is also generally redundant, and added to the noise.
