Maybe NFS should wait for the network to be up?

I had a similar problem with an nginx binded to a specific IP, it didn't start 
because the interface wasn't yet up, so I had to make a new unit and put this 
inside (/etc/systemd/system/nginx.service):

.include /usr/lib/systemd/system/nginx.service

After=network.target remote-fs.target nss-lookup.target network-online.target

The After line is the important one, I copied it from
/usr/lib/systemd/system/nginx.service and added "network-online.target"
at the end.

After making your changes, be sure to reenable the service so it takes your 
new unit, e.g.:

# systemctl reenable nginx.service

It worked for me, maybe it works for you?
