[PATCH v2 08/13] ext4: cleanup useless out tag in __es_remove_extent()

[Zhang Yi <yi.zhang@huaweicloud.com>]

From: Zhang Yi <yi.zhang@huawei.com>

The out tag in __es_remove_extent() is just return err value, we can
return it directly if something bad happens. Therefore, remove the
useless out tag and rename out_get_reserved to out.
