btrfs: subpage: rename macro variables to avoid shadowing

When compiling with -Wshadow there are warnings in the subpage helper
macros that are used in functions like btrfs_subpage_dump_bitmap() or
btrfs_subpage_clear_and_test_dirty() that also use 'bfs' (for struct
btrfs_folio_state) or blocks_per_folio.

Add '__' to the macro variables and unify naming in all subpage macros.
