drm/amd/display: Copy AUX read reply data whenever length > 0
commit 3924f45d4de7250a603fd7b50379237a6a0e5adf upstream.
[Why]
amdgpu_dm_process_dmub_aux_transfer_sync() should return all exact data
reply from the sink side. Don't do the analysis job in it.
[How]
Remove unnecessary check condition AUX_TRANSACTION_REPLY_AUX_ACK.
