Subject: [PATCH] obexd: Fix cann't receive small files sent by windows
Date:   Wed, 23 Mar 2022 11:36:12 +0800

Windows devices use streaming mode to send files. If a small file is
sent,the first time processing data will be completed successfully,
and the transfer_complete function will be called before the end to
clear os->path.At this time, the dbus signal is still pending, and
the dbus method call requesting the file path has not been processed;
in this way, the upper-level program will not be able to obtain the
file path, resulting in failure to receive the file.
Therefore, the signal of Filename is generated, and it is forced to
be sent when status=active.
