Subject: [Patch net 05/11] net: hns3: remove unnecessary queue reset in the hns3_uninit_all_ring()

It is not necessary to reset the queue in the hns3_uninit_all_ring(),
since the queue is stopped in the down operation, and will be resetted
in the up operaton. And the judgment of the HCLGE_STATE_RST_HANDLING
flag in the hclge_reset_tqp() is not correct, because we need to reset
tqp during pf reset, otherwise it may cause queue not be resetted to
working state problem.

Fixes: 76ad4f0ee747 ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC")
