  ovs-ofctl: Fix coredump when using "add-groups" command.

When using ovs-ofctl add-groups with only "switch" argument, a coredump
is generated.  The main reason is that the command "ovs-ofctl add-groups"
need two arguments but the limitation of min-args of this command is
set to 1.

Fixes: 7395c05254df ("Implement OpenFlow 1.1+ "groups" protocol.")
