cap file for the wrong PSM detected

Build Information:
Version 1.6.4 (SVN Rev 39941 from /trunk-1.6)
--
Please see the wrong_PSM_when_parsing_l2cap.cap for details.

At No.74, a connection request for PSM=SDP on SCID=0x40 is received. And then
at the next steps, a L2CAP link for SDP is established.

At No.85, a packet is received on the link of SCID=0x40. It should be parsed by
a SDP packet. But wireshark[PSM: AVDTP(0x0019] implies that is an AVDTP packet
and parses it wrong.
