Lorenz Bauer ffb9d5c48b bpf: verifier: Allocate idmap scratch in verifier env
commit c9e73e3d2b upstream.

func_states_equal makes a very short lived allocation for idmap,
probably because it's too large to fit on the stack. However the
function is called quite often, leading to a lot of alloc / free
churn. Replace the temporary allocation with dedicated scratch
space in struct bpf_verifier_env.
