At least 'nbd-client -l localhost' is a good demonstration of

client that legitimately sends NBD_OPT_ABORT - it exists only
to enumerate the exports advertised by the server, rather than
intending to connect to any of those exports. As such, we should
downgrade the message for a client telling us it is going away
to the same status as our debug message for NBD_CMD_DISC, given
that the two have the same effect at different points in the
protocol. This stops nbdkit from spamming stderr with
nbdkit: file[1]: error: client sent NBD_OPT_ABORT to abort the connection
messages due to a client that doesn't want to connect after all.

Found while implementing a similar 'qemu-nbd --list' that is
nicer than nbd-client's version ;)
