[PATCH 6/6] gen_nodes: ensure kdevops prefix has no dashes

[Luis Chamberlain <mcgrof@kernel.org>]

Folks trying to use kdevops and testing with fstests will quickly
find out a surprise that their config is not being parsed correctly
until later.

Fix this by preventing bringup if the prefix has a dash.

We use the dash to help parallelize testing filesystem profiles and
so the host prefix goes before the filesystem name and test profile.
