[PATCH 3/3] md/raid10: move rdev->corrected_errors counting

Read errors are considered to corrected if write-back and re-read
cycle is finished without further problems. Thus moving the rdev->
corrected_errors counting after the re-reading looks more reasonable
IMHO.

For end_sync_read(), I'm not sure what should I do. But I think, at
least, the counting should be moved to end_sync_write() and that
might require additional field(s) in r10_bio. So I leave it as is
for simplicity now. How do you think?
