I think I forgot to send the patch out, but it's been reverted in the
ext4 master branch, commit id: d9f34504e695. It's more than a revert,
actually, since I also dropped error checking for FITRIM. Otherwise
an attempt to use FITRIM would stop after hitting the first dm region
that didn't support discards.
