ASoC: SOF: ipc: check ipc return value before data copy
In tx_wait_done the ipc payload is copied before the DSP transaction error code is checked. This might lead to corrupted data in kernel side even though the error would be handled later. It is also pointless to copy the data in case of error. So change the order of error check and copy.
