[PATCH AUTOSEL 4.18 012/131] selftests/bpf: fix a typo in map in map test

[Sasha Levin]

From: Roman Gushchin <g...@fb.com>

[ Upstream commit 0069fb854364da79fd99236ea620affc8e1152d5 ]

Commit fbeb1603bf4e ("bpf: verifier: MOV64 don't mark dst reg unbounded")
revealed a typo in commit fb30d4b71214 ("bpf: Add tests for map-in-map"):
BPF_MOV64_REG(BPF_REG_0, 0) was used instead of
BPF_MOV64_IMM(BPF_REG_0, 0).

I've noticed the problem by running bpf kselftests.

Fixes: fb30d4b71214 ("bpf: Add tests for map-in-map")
