Too late for 2.5, need do this for HW_COMPAT_2_5. Just for pcie, another choice is a new type with "is_express = true". But both method looks good to me.

Following the previous patch which changed vmxnet3 to be a pci express device, this patch introduces a boolean property 'x-disable-pcie' whose default is false. Setting 'x-disable-pcie' to 'on' preserves the old 'pci device' (non express) behavior. This allows migration to older versions.
