btrfs-progs: check: introduce repair_extent_data_item()

The only thing repair_extent_data_item() does is that it adds backref of the
tree_block. Just like what original mode does:

It first searches the corresponding extent item.

1. If the extent item exists but backref is missing, add one backref to the
   extent.
2. Found nothing, just add an extent item and add one backref.
