[0/2] btrfs: add large folio support to read-repair and defrag

Message

These two patches are originally in a series of ASSERT()s cleanup, but
later since I'm able to enable large data folios for testing, one bug is
exposed in the first patch, thus these two are not yet merged into
for-next branch.

Now with full fstests able to run on my local large data folios branch,
I can eventually verify the behavior of those two patches.

The first patch is to add extra calculation to convert the bio_vec (no
matter single page or multi page) to a proper folio and offset inside the
folio.

The second patch is to add large folios support to defrag, which only
needs minor changes.

  btrfs: enable larger data folios support for defrag
