[PATCH BlueZ 1/4] android/AVDTP: Make signalling channel priority 6

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This makes signalling priority 6 so it can push commands before the
stream channel, without this the stream channel may be schedule
first and cause the signalling commands to timeout while waiting a slot.
