Re: [PATCH 3/5] AVRCP: respond with UINT32_MAX if duration is not available

Section 5.4.1 of AVRCP 1.3 spec says:

       If TG does not support SongLength And SongPosition on TG, then TG shall
       return 0xFFFFFFFF.

SongPosition is always available, but song length depends on user to
provied it.
