Subject: [PATCH - nfs-utils] Stop Treat IP addresses a FQDN rather than SUBNETs.



I think there was a reason for this many years ago,
but I can not find any evidence that it ever really did
anything useful and it certainly doesn't seem to now.

And the documentation suggests that IP address take precedence over
SUBNETs, and that can only happen if they are treated as MCL_FQDN.

So remove this apparently pointless code.
