ASoC: SOF: Intel: hda-stream: handle real stream interrupts only
The stream and IPC share the same interrupt. The stream interrupt handler mistakenly uses the ipc interrupt and return IRQ_HANDLED, causing the ipc interrupt to be missed. Make sure the stream interrupt handler only deals with stream-related interrupts.
