net: hns3: fix a memory leak issue for hclge_map_unmap_ring_to_vf_vector

[ Upstream commit 49f971bd308571fe466687227130a7082b662d0e ]

When hclge_bind_ring_with_vector() fails,
hclge_map_unmap_ring_to_vf_vector() returns the error
directly, so nobody will free the memory allocated by
hclge_get_ring_chain_from_mbx().

So hclge_free_vector_ring_chain() should be called no matter
hclge_bind_ring_with_vector() fails or not.
