[PATCH v2 1/9] Fix double free in error case in endpoint_reply

["Frédéric Dalleau" <frederic.dalleau@linux.intel.com>]

If SetConfiguration call fails, the headset or gateway for which
SetConfiguration is called is disconnected. This will free any
pending request, but this does not prevent the request to
terminate (endpoint_reply) and try to free itself once again.
Note that a copy of the freed pointer is tested which has not
been updated.
