Error message about no 32 bit addr space gap in x86 PCI code

VTL2 runs in 64bit mode, and its memory layout might be more generic than the x86 PCI code assumes. That leads to the errors

```
Cannot find an available gap in the 32-bit address range
message":"PCI devices with unassigned 32-bit BARs may not work!
```

Send a proper fix upstream, workaround by downgrading to INFO
