Eric Dumazet 4c450583d9 net: fix races in page->_count manipulation 
This is illegal to use atomic_set(&page->_count, ...) even if we 'own'
the page. Other entities in the kernel need to use get_page_unless_zero()
to get a reference to the page before testing page properties, so we could
loose a refcount increment.

The only case it is valid is when page->_count is 0

Fixes: 540eb7bf0bbed ("net: Update alloc frag to reduce get/put page usage and recycle pages")
