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

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.
