Fix flower destroy template callback to release template
only for specific tc chain instead of all chain tempaltes.
The issue was intruduced by previous commit that introduced
multi-chain support.
Fixes: fa5d824ce5dd ("net: prestera: acl: add multi-chain support offload")
Signed-off-by: Volodymyr Mytnyk <vmytnyk@marvell.com>
