[nvme-cli 9/9] tests/nvme_format_test.py: skip test if namespace management is not supported

[hare@suse.de (Hannes Reinecke)]

While the spec doesn't make any explicit reference to namespace management,
the 'format' command itself is optional, and as such should be allowed
to fail. And the test requires the use of the controller identifier, which
in itself requires namespace management.
So add a check for namespace management before executing the tests.
