btrfs: support subpage in btrfs_clone_extent_buffer
For btrfs_clone_extent_buffer(), it's mostly the same code of __alloc_dummy_extent_buffer(), except it has extra page copy. So to make it subpage compatible, we only need to: - Call set_extent_buffer_uptodate() instead of SetPageUptodate() This will set correct uptodate bit for subpage and regular sector size cases. Since we're calling set_extent_buffer_uptodate() which will also set EXTENT_BUFFER_UPTODATE bit, we don't need to manually set that bit either.
