hw/virtio/vhost-vdpa: Use target-agnostic qemu_target_page_mask()

Browse source 
Similarly to commit e414ed2c47 ("virtio-iommu: Use
target-agnostic qemu_target_page_mask"), Replace the
target-specific TARGET_PAGE_SIZE and TARGET_PAGE_MASK
definitions by a call to the runtime qemu_target_page_size()
helper which is target agnostic.
