Fix an incorrect sizeof() usage in sst_hsw_stream_get_volume(). sst_dsp_read()
is called to read into a variable of type u32, but is passed sizeof(u32 *) for
argument 'size_t bytes'. Detected by Coverity: CID 1195260.

There are a couple others in this file. I introduced one of them. :(
Sorry about that. I'll send a patch for that.

The intent was to say "sizeof(*pos)" and not "sizeof(pos)".
The sizeof(*pos) is 8 bytes so the bug won't show up on 64 bit systems.
The sizeof(*dx) is 172 bytes so that will be a bugfix.
