net: hns3: fix error handling int the hns3_get_vector_ring_chain
When hns3_get_vector_ring_chain() failed in the hns3_nic_init_vector_data(), it should do the error handling instead of return directly. Also, cur_chain should be freed instead of chain and head->next should be set to NULL in error handling of hns3_get_vector_ring_chain. This patch fixes them.
