Description of problem:
Failed to update the VFs configuration of network interface card type 82599ES and X520

RHEL HOST INFO:
vdsm-4.40.80.6-1.el8ev.x86_64
libvirt-7.6.0-3.module+el8.5.0+12510+80564ecf.x86_64

kernel-4.18.0-340.el8.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Prepare a registerted rhv node with SRIOV support
Tab Compute -> Hosts -> Edit(eg:host-a) -> Kernel : choose Hostdev Passthrough & SR-IOV(and add intel_iommu=on or amd_iommu=on in 'Kernel command line'); save configurations.
Management -> Maintenance host; Installation -> reinstall, then active the sriov host again.

The host ethernet info - 82:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

2. Tab Networks :
New -> new a logical network	

3. Change network profile to passthrough
Tab Networks :
Network->vNIC Profiles (Select newly added ‘sriov-test’ network)->Edit
->choose Passthrough.

Then save configurations.
	
4. Tab Compute ->Hosts - > Network interface -> Setup Host Networks
Choose the interface with SR-IOV tag; edit
Click Number of VF Setting: set the number
Drag ( eg: testa) to a PF on the left part, then save the configuration.


Actual results:
Failed to save the configuration with the error message:
"""
Operation Canceled
Error while executing at least some of the action tasks:

enp130s0f0:
Failed to change the number of virtual functions.
"""

Expected results:
Fix it.

2. I will attach the vdsm.log got from the registered host.

3. I can also reproduce this issue with SRIOV card type - "Ethernet controller: Intel Corporation Ethernet 10G 2P X520 Adapter (rev 01)"

4. I can't reproduce this issue with SRIOV card type - "Ethernet controller: Mellanox Technologies MT2892 Family [ConnectX-6 Dx]".
