arm64: bpf: fix div-by-zero case
commit 251599e1d6906621f49218d7b474ddd159e58f3b upstream.
In the case of division by zero in a BPF program:
A = A / X; (X == 0)
the expected behavior is to terminate with return value 0.
This is confirmed by the test case introduced in commit 86bf1721b226
("test_bpf: add tests checking that JIT/interpreter sets A and X to 0.").
