mboxd_dbus: Handle errors in reply path

We were seeing some odd errors in the journal, for example:

	dbus[736]: [system] Rejected send message, 0 matched rules; type="error", sender=":1.14" (uid=0 pid=773 comm="/usr/sbin/mboxd --flash 64M --verbose --window-siz") interface="(unset)" member="(unset)" error name="org.freedesktop.DBus.Error.UnknownMethod" requested_reply="0" destination=":1.123" (uid=0 pid=2157 comm="/usr/sbin/mboxctl --reset ")

However, coinciding with the deployment of the patched mboxd the errors
went away. This patch shouldn't fix whatever was going on, but at
least we might see some report of problems in the reply codepath if it
occurs again in the future.
