bpf: dev_map_alloc() shouldn't return NULL
We forgot to set the error code on two error paths which means that we
return ERR_PTR(0) which is NULL. The caller, find_and_alloc_map(), is
not expecting that and will have a NULL dereference.
Fixes: 546ac1ffb70d ("bpf: add devmap, a map for storing net device references")
