Liu Jian 22771d3095 bpf: Enlarge offset check value to INT_MAX in bpf_skb_{load,store}_bytes ...

commit 45969b4152 upstream.

The data length of skb frags + frag_list may be greater than 0xffff, and
skb_header_pointer can not handle negative offset. So, here INT_MAX is used
to check the validity of offset. Add the same change to the related function
skb_store_bytes.

Fixes: 05c74e5e53 ("bpf: add bpf_skb_load_bytes helper")
