dracut: nbd: Only complain of missing binary in hostonly mode if

 rootfs is on nbd

In not hostonly mode, require_binaries will still complain.
If in hostonly mode and the module is explicitly added via -a nbd, then
install() section will still complain later:
dracut-install: ERROR: installing 'nbd-client'
