When the host has enabled the udev/systemd autoconnect services for the
fc transport it interacts with blktests and make tests break.
nvme-cli learned to ignore connects attemps when using the --context
command line option paired with a volatile configuration. Thus we can
mark all the resources created by blktests and avoid any interaction
with the systemd autoconnect scripts.
Only enabled this for the fc transport.
