[Qemu-devel] [PATCH] vfio/pci: Allow MSI-X relocation to fixup bogus PBA

[Alex Williamson]

The MSI-X relocation code can sometimes be used to work around bogus
MSI-X capabilities, but this test for whether the PBA is outside of
the specified BAR causes the device to error before we can apply a
relocation.  Let it proceed if we intend to relocate MSI-X anyway.
