Document the current semantics of the 'quiet' command prefix in the rc.subr(8). Fix dhclient rc.d script: it should not call err() for non-DHCP-enabled interface when it is called from devd, because the latter just blindly calls 'service dhclient quietstart' on each "link up" event. Since the 'quietstart' will silence the message "Cannot 'start' <foo>. Set <foo>_enable to YES in /etc/rc.conf or use 'onestart' instead of 'start'." and running dhclient on the non-DHCP-enabled interface is the same thing as running the service <foo> without <foo>_enable set, such modification is in sync with the current semantics of the 'quiet' prefix.
