[PATCH] ASoC: qcom: q6apm: Fix the wait for SHARED_MEM_UNMAP_REGIONS

[redducc]

The DSP acknowledges APM_CMD_SHARED_MEM_UNMAP_REGIONS with a
GPR_BASIC_RSP_RESULT packet. apm_callback() stores the packet opcode,
GPR_BASIC_RSP_RESULT, as the result opcode, but
audioreach_send_cmd_sync() waits for the result opcode to match the
command, APM_CMD_SHARED_MEM_UNMAP_REGIONS. The wait never completes,
so every unmap blocks for the full 5 s timeout and logs
"CMD timeout".

Store the opcode of the command being acknowledged, as the other
GPR_BASIC_RSP_RESULT cases already do.
