[PATCH] audio: Fix AVDTP General Reject message

[Mike Brudevold <puffy.taco@gmail.com>]

From: Michael Brudevold <michael.brudevold@logicpd.com>

As per spec, bits other than Transaction Label and Packet Type are RFA. This
fixes the RFA bits which were previously set to the invalid signal_id.

Test case TP/SIG/SMG/BI-28-C.
