cephadm: black format net_utils.py

This contains one small manual change reversing the black formatting.
According to the black docs [1], flake8's E203 is not pep8 compliant but
since flake8 is currently mandatory and black formatting is not we'll
leave it in a form that makes flake8 happy and attempt to resolve the
disagreement some time in the future.
