[PATCH 2/6] Btrfs: use more straightforward extent_buffer_uptodate

[Liu Bo <bo.liu@linux.alibaba.com>]

In read_block_for_search(), it's straightforward to use
extent_buffer_uptodate() instead since 0 is passed as parent transid to
btrfs_buffer_uptodate(), which means the check for parent transid is not
needed.
