xscale: fix bug in xscale_receive() 

The code in xscale_receive() that tries to skip invalid reads (i.e.
reads that don't have the DBG_SR[0] 'valid' bit set) seems to be
wrong, as it only looks at the first word's valid flag rather than
each word's own valid flag. Am I reading the code correctly? If so,
the attached patch should fix it.

If this looks correct, I'll generate a proper patch and commit message.
