net: hns3: fix user's coalesce configuration lost issue

mainline inclusion
from mainline-v5.13-rc4
commit 73a13d8d
category: bugfix
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=73a13d8dbe33e53a12400f2be0f5af169816c67f



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

Currently, when adaptive is on, the user's coalesce configuration
may be overwritten by the dynamic one. The reason is that user's
configurations are saved in struct hns3_enet_tqp_vector whose
value maybe changed by the dynamic algorithm. To fix it, use
struct hns3_nic_priv instead of struct hns3_enet_tqp_vector to
save and get the user's configuration.

BTW, operations of storing and restoring coalesce info in the reset
process are unnecessary now, so remove them as well.
