net/failsafe: skip devargs if not present in secondary

When secondary process is run was noticing that the log always
contained complaints about unable to parse devargs.

It turns out that an empty devargs turns into "" and this
value is not parsable. Change the failsafe secondary to just
skip doing devargs if it empty.
