Running dracut when the root device is not known to zdev (for example because it is located on a virtio block device) will cause the zdev dracut module to incorrectly return an error in the installkernel() function. As a result dracut aborts with an error. Fix this by ensuring that the non-zero exit code resulting from lszdev not being able to determine the root device is not passed on to the calling function. Also remove unnecessary error output in this case by leaving the install() function early when the root device is not known to zdev.
