Cosmetic change to 'virsh nodedev-list --tree' output
Cosmetic change to 'virsh nodedev-list --tree' output

Maybe it's just me, but I try to select an item from the tree using
double-click and get annoyed when "+-" gets included in the selection.

* src/virsh.c: add a space between "+-" and the node device name
  in 'virsh nodedev-list --tree'
