Zi Shen Lim 251599e1d6 arm64: bpf: fix div-by-zero case
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 86bf1721b2
("test_bpf: add tests checking that JIT/interpreter sets A and X to 0.").
