gve: change to use page_pool_put_full_page when recycling pages

The driver currently uses page_pool_put_page() to recycle
page pool pages. Since gve uses split pages, if the fragment
being recycled is not the last fragment in the page, there
is no dma sync operation. When the last fragment is recycled,
dma sync is performed by page pool infra according to the
value passed as dma_sync_size which right now is set to the
size of fragment.

But the correct thing to do is to dma sync the entire page when
the last fragment is recycled. Hence change to using
page_pool_put_full_page().
