The Q35 + OVMF L2 VM with a igbvf throws "VFIO_MAP_DMA failed: Invalid argument, vfio_dma_map= -22 (Invalid argument)" error

Please provide the package NVR for which bug is seen:
host:
qemu-kvm-8.1.0-4.el9.x86_64
edk2-ovmf-20230524-4.el9_3.noarch
L1:
qemu-kvm-8.1.0-4.el9.x86_64
edk2-ovmf-20230524-4.el9_3.noarch

How reproducible:
100%

Steps to reproduce
[1] start a Q35 + OVMF L1 VM with a emulated igb + intel iommu
[2] create a VF from the emulated igb in the L1 VM
[3] make sure the iommu is enabled in the L1 VM
[4] start a Q35 + OVMF L2 VM with a igbvf
[5] do ping tests
[6] check the qemu-kvm and kernel log
The L1 qemu-kvm throws the following error:

Expected results
No qemu-kvm error

Actual results
The qemu-kvm throws the error"VFIO_MAP_DMA failed: Invalid argument. vfio_dma_map(0x56436cc15ae0, 0x383000004000, 0x4000, 0x7f2330000000) = -22 (Invalid argument)"

Additional info:

(1) After changing the L2 firmware from "efi" to "seabios", the qemu-kvm error gone.
