net: hns3: fix get wrong value of function hclge_get_dscp_prio()

mainline inclusion
from mainline-master
commit cfdcb075
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5ZXH9
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cfdcb075048c1e886c45a9c9e681ed222f74ecb9



----------------------------------------------------------------------

As the argument struct hnae3_handle *h of function hclge_get_dscp_prio()
can be other client registered in hnae3 layer, we need to transform it
into hnae3_handle of local nic client to get right dscp settings for
other clients.
