Introduce the following functions to handle subpage error status:
- btrfs_subpage_set_error()
- btrfs_subpage_clear_error()
- btrfs_subpage_test_error()
These helpers can only be called when the page has subpage attached
and the range is ensured to be inside the page.
- btrfs_page_set_error()
- btrfs_page_clear_error()
- btrfs_page_test_error()
These helpers can handle both regular sector size and subpage without
problem.
