Cited patch in the fixes tag clears the features bit during reset.
mlx5 vdpa device feature bits are static decided by device capabilities.
These feature bits (including VIRTIO_NET_F_MAC) are initialized during
device addition time.
Clearing features bit in reset callback cleared the VIRTIO_NET_F_MAC. Due
to this, MAC address provided by the device is not honored.
Fix it by not clearing the static feature bits during reset.
