vmxnet3: Introduce 'x-old-msi-offsets' back-compat property

Browse source 
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.
