From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently when txmsg fails to allocate then there is a leak on 'out'. Fix
this by setting result to false and exiting via the clean up exit path.
Note since txmsg is NULL at this point, the kfree of txmsg is a no-op.
Addresses-Coverity: ("Resource leak")
Fixes: 09234b88ef55 ("drm/selftests/test-drm_dp_mst_helper: Move 'sideband_msg_req_encode_decode' onto the heap")
