btrfs: add helpers to get inode from page/folio pointers
[ Upstream commit c8293894afa718653688b2fa98ab68317c875a00 ]
Add convenience helpers to get a struct btrfs_inode from a page or folio
pointer instead of open coding the chain or intermediate BTRFS_I. This
is implemented as a macro (still with type checking) so we don't need
full definitions of struct page or address_space.
