Current set_btree_ioerr() only accepts @page parameter and grabs extent buffer from page::private. This works fine for sector size == PAGE_SIZE case, but not for subpage case. Adds an extra parameter, @eb, for callers to pass extent buffer to this function, so that subpage code can reuse this function. And also add subpage special handling to update btrfs_subpage::error_bitmap.
