Ning Ding 83608e303b bpf: Compare iterator types during state pruning
An iterator stack slot can be MEM_RCU or PTR_UNTRUSTED. These states
must not be equal, or the verifier can prune an unsafe path.

Compare the pointer type for STACK_ITER slots.

Fixes: dfab99df14 ("bpf: teach the verifier to enforce css_iter and task_iter in RCU CS")
