Liu Bo ca19b4a699 Btrfs: remove superfluous free_extent_buffer in read_block_for_search 
read_block_for_search() can be simplified as:

tmp = find_extent_buffer();
if (tmp)
   return;

...

free_extent_buffer();
read_tree_block();

Apparently, @tmp must be NULL at this point, free_extent_buffer() is not
needed.
