vmxnet3: Introduce 'x-old-msi-offsets' back-compat property
Following the previous patches, where vmxnet3's pci's msi/msix capability offsets and msix's PBA table offsets have been changed, this patch introduces a boolean property 'x-old-msi-offsets' to vmxnet3, whose default is false. Setting 'x-old-msi-offsets' to 'on' preserves the old offsets behavior, which allows migration to older versions.
