nvme: ignore non-PCI NVMe devices
nvme: ignore non-PCI NVMe devices

Ignore non-PCI NVMe devices (e.g. NVMe-over-Fabrics) when probing.
Otherwise, logs might be flooded with error messages:

03:10:53:0251 FuEngine             failed to add device /sys/devices/virtual/nvme-fabrics/ctl/nvme1: failed to find device with subsystems pci, only got nvme,nvme-fabrics

These devices are not supported as they are not on the PCI subsystem.
