ASoC: qcom: q6asm: handle the responses after closing

For record path, multiple read requests are queued to dsp in advance.
However when data stream is closed, the pending read requests are rejected
by the dsp and a response is sent to the driver, this case is not handled
in the driver resulting in errors like below

q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: command[0x10dac] not expecting rsp
q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: command[0x10dac] not expecting rsp
q6asm-dai ab00000.remoteproc:glink-edge:apr:service@7:dais: command[0x10dac] not expecting rsp

This is same for both write and eos.

Fix this by allowing ASM_DATA_CMD_READ_V2, ASM_DATA_CMD_EOS and
ASM_DATA_CMD_WRITE_V2 as expected response.
