The ChainDMA operation differs from normal pipelines that it is only
created when the stream started, in fact a PCM using ChainDMA has no
pipelines, modules.
To reset a ChainDMA, it needs to be first allocated in firmware. When
PulseAudio/PipeWire starts, they will probe the PCMs by opening them, check
hw_params and then close the PCM without starting audio.
Unconditionally resetting the ChainDMA can result the following error:

ipc tx      : 0xe040000|0x0: GLB_CHAIN_DMA
ipc tx reply: 0x2e000007|0x0: GLB_CHAIN_DMA
FW reported error: 7 - Unsupported operation requested
ipc error for msg 0xe040000|0x0
sof_pcm_stream_free: pcm_ops hw_free failed -22

Add a new chain_dma_allocated flag to sof_ipc4_pcm_stream_priv to store the
ChainDMA allocation state and use this flag to skip sending the reset if
the ChainDMA is not allocated.
