btrfs: unify the error handling of btrfs_read_buffer()

There is one oddball error handling of btrfs_read_buffer():

ret = btrfs_read_buffer(tmp, gen, parent_level - 1, &first_key);
if (!ret) {
*eb_ret = tmp;
return 0;
}
free_extent_buffer(tmp);
btrfs_release_path(p);
return -EIO;

While all other call sites check the error first.  Unify the behavior.
