page_pool: make sure struct device is stable
For DMA mapping use-case the page_pool keeps a pointer
to the struct device, which is used in DMA map/unmap calls.
For our in-flight handling, we also need to make sure that
the struct device have not disappeared. This is assured
via using get_device/put_device API.
