md: make sure read errors are auto-corrected during a 'check' resync in raid1
Whenever a read error is found, we should attempt to overwrite with correct
data to 'fix' it.
However when do a 'check' pass (which compares data blocks that are
successfully read, but doesn't normally overwrite) we don't do that. We
should.
