erofs: allow large folios for compressed files
As commit 2e6506e1c4ee ("mm/migrate: fix deadlock in
migrate_pages_batch() on large folios") has landed upstream, large
folios can be safely enabled for compressed inodes since all
prerequisites have already landed in 6.11-rc1.
Stress tests has been running on my fleet for over 20 days without any
regression. Additionally, users [1] have requested it for months.
Let's allow large folios for EROFS full cases upstream now for wider
testing.
