Subject: [PATCH -next v2 09/14] btrfs: convert try_release_extent_mapping() to take a folio

The old page API is being gradually replaced and converted to use folio
to improve code readability and avoid repeated conversion between page
and folio. And page_to_inode() can be replaced with folio_to_inode() now.
