Liam Girdwood f69f41e1a2 ASoC: Intel: Check Haswell IPC process_reply/notification return value. 
Check the return value for error when processing replies and notifications.

The patch 2298124358: "ASoC: Intel: Add Haswell/Broadwell IPC" from
> Feb 20, 2014, leads to the following imaginary static checker warning:
>
> 	sound/soc/intel/sst-haswell-ipc.c:898 hsw_irq_thread()
> 	warn: this is always true.

> sound/soc/intel/sst-haswell-ipc.c
>    895                  /* Handle Immediate reply from DSP Core */
>    896                  handled = hsw_process_reply(hsw, ipcx);
>                                   ^^^^^^^^^^^^^^^^^
> Returns 1 on success/error and -EIO on error.
