It is possible that generic_bin_search will be called on a tree block
that has not been locked. This happens because cache_block_block skips
locking on the tree blocks.
Since the tree block isn't locked, we aren't allowed to change
the extent_buffer->map_token field. Using map_private_extent_buffer
avoids any changes to the internal extent buffer fields.
