ASoC: SOF: ipc4-topology: restore gateway config length

Browse source

The initial code had a logic flaw where the gateway config length kept
increasing after each playback/capture trigger, with the DMA config
TLV being added at every call of sof_ipc4_prepare_copier_module()

This didn't cause any issues with regular playback/capture, but this
was flagged as an error by firmware in the case of multiple amplifiers
on different links.
