core/ovs: fix setting dpdk-devargs JSON to NULL

Browse source 
NMSettingOvsDpdk does not have a verify() implementation that would prevent
the devargs property from being NULL. We must thus anticipate and handle
a NULL value.

Fixes: ae4152120a ('ovs/ovsdb: add support for setting dpdk devargs option')
