Subject: net: hns3: remove unnecessary queue reset in the
hns3_uninit_all_ring()
Patch-mainline: v4.20-rc1
Git-commit: 5faaf0752a0c43735b7c508dcf3c4c7b36a032db
References: bsc#1104353 FATE#326415
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 reset
in the up operation. 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 being reset to
working state problem.
