Alexei Starovoitov 1336c66247 bpf: Clear per_cpu pointers during bpf_prog_realloc ...

bpf_prog_realloc copies contents of struct bpf_prog.
The pointers have to be cleared before freeing old struct.

Reported-by: Ilya Leoshkevich <iii@linux.ibm.com>
Fixes: 700d4796ef ("bpf: Optimize program stats")
Fixes: ca06f55b90 ("bpf: Add per-program recursion prevention mechanism")
