drm/selftests/test-drm_dp_mst_helper: Move 'sideband_msg_req_encode_decode' onto the heap
There is too much data being stored on the stack.
Fixes the following W=1 kernel build warning(s):
drivers/gpu/drm/selftests/test-drm_dp_mst_helper.c: In function ‘sideband_msg_req_encode_decode’:
drivers/gpu/drm/selftests/test-drm_dp_mst_helper.c:168:1: warning: the frame size of 1072 bytes is larger than 1024 bytes [-Wframe-larger-than=]
