Eduard Zingerman 16698b1ef2 bpf: abort verification if env->cur_state->loop_entry != NULL 
[ Upstream commit f3c2d243a3 ]

In addition to warning abort verification with -EFAULT.
If env->cur_state->loop_entry != NULL something is irrecoverably
buggy.

Fixes: bbbc02b744 ("bpf: copy_verifier_state() should copy 'loop_entry' field")
