fix(74nvmf): set root=nvmf

In a restricted image like kdump the kernel commandline argument root=
is typically absent. However it is required by the 45net-lib/netroot.sh
module that fails with:

    [   23.599862] dracut: FATAL: No or empty root= argument
    [   23.604956] dracut: Refusing to continue

Inspired by the 74iscsi module, let's set it to root=nvmf if not set
before.
