dracut-module-setup: remove old s390 network device config (#1937048)

Browse Source 
Since the previous commit reworks znet configuration to be based on the
active system configuration, there is no dependency on any existing
persistent configuration any more. Hence the old code handling systems with
exactly one s390-specific nmconnection as persistent configuration can be
removed.

Migration of the old persistent device configuration mechanism with
nmconnections (or ifcfg) to zdev is handled independently in s390utils.

 ("znet: migrate to consolidated persistent device config with zdev
   (#1937046,#1937048))"]
