Since VF pci device is dependent on PF pci device, When PF pci device

problem, VF pci device should be removed before PF pci device is removed.
This patch moves pci_enable/disable_sriov from hclge to hns3 to solve

Because the current statistics for size 8192~12287 are only valid for GE,
the ranges of 8192~9216 and 9217~12287 are valid only for LGE/CGE, and are
always 0 for GE interfaces. it is easy to cause confusion when viewing the
packet statistics using the command ethtool -S.
This patch removes the 8192~12287 range of packet statistics and uses the
8192~9216 and 9217~12287 ranges for statistics. This change depends on the
firmware upgrade.

There are two level of vlan tables in hardware, one is port vlan
which is shared by all functions, the other one is function
vlan table, each function has it's own function vlan table.
Currently, PF sets the port vlan table, and vf sets the function
vlan table, which will cause packet lost problem.
This patch fixes this problem by setting both vlan table, and
use hdev->vlan_table to manage thet port vlan table.
