bpf: abort verification if env->cur_state->loop_entry != NULL
commit f3c2d243a36ef23be07bc2bce7c6a5cb6e07d9e3 upstream.
In addition to warning abort verification with -EFAULT.
If env->cur_state->loop_entry != NULL something is irrecoverably
buggy.
Fixes: bbbc02b7445e ("bpf: copy_verifier_state() should copy 'loop_entry' field")
