bpf/verifier: fix min/max handling in BPF_SUB
[ Upstream commit 9305706c2e808ae59f1eb201867f82f1ddf6d7a6 ]
We have to subtract the src max from the dst min, and vice-versa, since
(e.g.) the smallest result comes from the largest subtrahend.
Fixes: 484611357c19 ("bpf: allow access into map value arrays")
