hmp: Add nbd_server_remove to mirror QMP command
Since everything else about the nbd-server-* QMP commands is
accessible from HMP, we might as well make removing an export
available as well. For now, I went with a bool flag rather
than a mode string for choosing between safe (default) and
hard modes.
