vzctl set --devnodes: fix removing last device
Apparently removing a last device from the list is a special case,
as merge_conf() doesn't detect it unless we provide some string.
So, let's print DEVNODES="" in this case.
This fixes the following bug:
# grep DEVNODES /etc/vz/conf/101.conf
DEVNODES="ttyS3:rw "
# vzctl set 101 --devnodes ttyS3:none --save
No changes in CT configuration, not saving
# grep DEVNODES /etc/vz/conf/101.conf
DEVNODES="ttyS3:rw "
