[hns-1125]net: hns3: remove upgrade reset level when reset fail

[Fred Kimmy]

"[Bug Description]
Currently, hclge_reset_err_handle() will assert a global reset
when the failing count is smaller than MAX_RESET_FAIL_CNT, which
will affect other running functions.

[Steps to Reproduce]
1.load PF/VF driver and enable VF
2.trigger PF global reset periodically by script
3.config PF/VF parameters periodically by script

[Actual Results]
Some ports run abnormally or stop running.

[Expected Results]
All ports run normally.

[Reproducibility]
Inevitably

[Additional information]
Hardware: D06
Firmware: NA
Kernel: NA

[Resolution]
This patch removes this upgrading, and uses re-scheduling reset
task to do it."

1) every PF port to set this 31 VF
 example: echo 31 > /sys/bus/pci/devices/0000\:7d\:00.0/sriov_numvfs

2) some net port connect this CX4 and 1822 net card, other net port connect this TESGINE network device

3) CX4 and 1822 net card send this UDP package; Tesgine send diff type package;
