[PATCH] bpf: testing: fix devmap tests

[John Fastabend]

Apparently through one of my revisions of the initial patches
series I lost the devmap test. We can add more testing later but
for now lets fix the simple one we have.

Fixes: 546ac1ffb70d "bpf: add devmap, a map for storing net device references"

Forgot prefix, this is for net-next. Sorry about that.
