Patches from Andrey Albershteyn to prepare for XFS fsverity support:
- Report verification errors through fserror, instead of only through
an unstructured log message and generic I/O error return
- Move the reporting of STATX_ATTR_VERITY into the VFS, so that each
fsverity-capable filesystem doesn't need to do it. This also fixes a
bug where btrfs didn't return STATX_ATTR_VERITY in attributes_mask
- Make the VFS prevent enabling DAX on fsverity files, so that it will
be handled in a single place for ext4 and XFS
- Move ext4 and f2fs's code to read verity metadata from the pagecache
into shared code, so that XFS will be able to use it too
- Export fsverity_ensure_verity_info() for XFS scrub to use
- Pass all-zeroes hash to ->write_merkle_tree_block() so that XFS will
be able to implement an optimization for sparse files
