net: kunit: test netmem, page_pool, and skb frag refcounting
Verify that non-pp (page._refcount / binding->ref) and page_pool
(pp_ref_count) references stay balanced without cross-counter leaks or
underflows across regular pages, page_pool pages, non-pp net_iovs, and
page_pool net_iovs with both pp_recycle=0 and pp_recycle=1.
Cover get/put_net_iov(), get/put_netmem(), napi_pp_get/put_page(),
skb_netmem_ref/unref(), skb_frag_ref/unref(), pskb_copy(),
skb_zerocopy(), skb_shift(), skb_split(), skb_try_coalesce(),
skb_release_data() (clones, unclone ordering, pskb_extract(), and
skb_morph()), skb_segment(), and devmem tcp_recvmsg_dmabuf() /
SO_DEVMEM_DONTNEED.
Export skb_shift() via EXPORT_SYMBOL_IF_KUNIT() so the test links when
built as a module (CONFIG_NET_TEST=m).
