Christoph Hellwig e2e401c50c iscsi-test-cu: support arbitrary device nodes ...

We support SG_IO on various block devices, including but not limited to:
SCSI disks, CDROMs and tapes, virtio-blk and nvmve.

Instead of checking a filename prefix just treat anything that isn't
an iscsi:// url as a device node.  The ioctl checks after open will weed
out devices (or files) that don't support SG_IO.
