Subject: [PATCH] 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'

Signed-off-by: Thomas Renninger <trenn@suse.de>
(cherry picked from commit e683985d103f1b0f15a9ccd9678169f4fb7aeb5f)
