We hit a following exception on timeout, nmaps is never set:

    Test bpftool bound info reporting (own ns)...
    Traceback (most recent call last):
      File "/home/virtme/testing-1/tools/testing/selftests/net/./bpf_offload.py", line 1128, in <module>
        check_dev_info(False, "")
      File "/home/virtme/testing-1/tools/testing/selftests/net/./bpf_offload.py", line 583, in check_dev_info
        maps = bpftool_map_list_wait(expected=2, ns=ns)
      File "/home/virtme/testing-1/tools/testing/selftests/net/./bpf_offload.py", line 215, in bpftool_map_list_wait
        raise Exception("Time out waiting for map counts to stabilize want %d, have %d" % (expected, nmaps))
    NameError: name 'nmaps' is not defined
