Gao Xiang 4127caee89 erofs: apply proper VMA alignment for memory mapped files on THP ...

There are mainly two reasons that thp_get_unmapped_area() should be
used for EROFS as other filesystems:

 - It's needed to enable PMD mappings as a FSDAX filesystem, see
   commit 74d2fad133 ("thp, dax: add thp_get_unmapped_area for pmd
   mappings");

 - It's useful together with large folios and
   CONFIG_READ_ONLY_THP_FOR_FS which enable THPs for mmapped files
   (e.g. shared libraries) even without FSDAX.  See commit 1854bc6e24
   ("mm/readahead: Align file mappings for non-DAX").

Fixes: 06252e9ce0 ("erofs: dax support for non-tailpacking regular file")
Fixes: ce529cc25b ("erofs: enable large folios for iomap mode")
Fixes: e6687b8922 ("erofs: enable large folios for fscache mode")
