Subject: net: hns3: remove hclge_get_vector_index from
 hclge_bind_ring_with_vector
Patch-mainline: v4.19-rc1
Git-commit: b204bc74840080136bf11643e998dc83afc2c11e
References: bsc#1104353 FATE#326415

In hclge_unmap_ring_frm_vector, there are 2 steps:
step 1: get vector index.
step 2 unbind ring with vector.

But it gets vector id again in step 2 interface. This patch
removes hclge_get_vector_index from hclge_bind_ring_with_vector,
and make the step the same with hns3 PF driver.
