Variables 'nval' and 'i' are no longer used sdw_master_read_intel_prop()
so remove them.

drivers/soundwire/intel.c: In function 'sdw_master_read_intel_prop':
drivers/soundwire/intel.c:829:12: warning: unused variable 'i' [-Wunused-variable]
  int nval, i;
            ^
drivers/soundwire/intel.c:829:6: warning: unused variable 'nval' [-Wunused-variable]
  int nval, i;
      ^~~~

This was fixed in the followup patch to disable hw links:

-	int nval, i;
+	u32 quirk_mask;

which wasn't applied because debugsfs didn't apply, and debugfs didn't 
apply because of discrepancies between soundwire/fixes and soundwire/next...
I realize these variables were removed in the wrong patch but I would 
appreciate it if we could just avoid creating more conflicts for minor 
changes. Thank you.

Well it is my mistake, the patch 085f4ace103d should not have kept it
and I should have pointed it out in the review
That would be the correct thing to do for a series.

Changing after is not really desired. I understand that this goes away
if that patch was merged but the point of a series is that we can find
issues in patch N but still be able to apply patches N-1.
