ofproto-dpif-upcall: fix for segmentation fault
Added check for NULL pointer on return from xlate_lookup_ofproto
function. Access to "ofproto" variable when NULL was causing segmentation
fault.
VMware-BZ: #2061914
CC: Justin Pettit <jpettit@ovn.org>
Fixes: d39ec23de384 ("ofproto-dpif: Don't slow-path controller actions.")
