Subject: [PATCH 105/283] net: hns3: add hns3_state_init() to do state
 initialization

mainline inclusion
from mainline-v5.15-rc1
commit c511dfff4b655685d7341962a76d9a340150e0ac
category: feature
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EMYT
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c511dfff4b655685d7341962a76d9a340150e0ac

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

To improve the readability and maintainability, add hns3_state_init() to
initialize the state, and this new function will be used to add more state
initialization in the future.
