[PATCH 2/2] AVCTP: Replace calls to g_queue_free_full function

[Giovanni Gherdovich <g.gherdovich@gmail.com>]

The function g_queue_free_full is available only from GLib 2.32.
If BlueZ has to build against GLib 2.28, as stated in the configure.ac,
this patch replaces the calls to g_queue_free_full in the AVTCP module
with its body, taken from the sources of GLib 2.32.
