Current check_file_extent() doesn't support later repair work, since it
doesn't accept btrfs_path structure as parameter, thus it can't modify
btrfs trees, or later check will still use the old and wrong path.
Use btrfs_path to replace btrfs_key, extent_buffer and slot parameters,
so we can modify @path directly for repair, and reduce the number of
parameters for check_file_extent().
