[PATCH 05/12] thunderbolt: Release request if tb_cfg_request() fails in __tb_xdomain_response()

[Mika Westerberg <mika.westerberg@linux.intel.com>]

If tb_cfg_request() fails setting up the request (for example the
control channel is shut down already) it returns an error without
calling the callback. To avoid leaking that memory, call
tb_cfg_request_put() if tb_cfg_request() fails.
