PCI: Add pci reset quirk for Huawei Intelligent NIC virtual function

driver inclusion
category: bugfix
bugzilla: NA

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

When multiple VFs do FLR at the same time, the firmware is
processed serially, resulting in some VF FLRs being delayed more
than 100ms, when the virtual machine restarts and the device
driver is loaded, the firmware is doing the corresponding VF
FLR, causing the driver to fail to load.

To solve this problem, add host and firmware status synchronization
during FLR.
