In fact, "none" would be accepted by strtobool() as a false (seeing it
starts with 'n' and strtobool() only looks at the first character).
However, per the rest of your feedback I've changed show() to report
"0", "1" or pci_name() and dropped "auto". This matches what the other
strtobool configfs attributes are doing in NVMe target.
