openvswitch: fix odd_ptr_err.cocci warnings
net/openvswitch/vport-gre.c:188:5-11: inconsistent IS_ERR and PTR_ERR, PTR_ERR on line 189 PTR_ERR should access the value just tested by IS_ERR Semantic patch information: There can be false positives in the patch case, where it is the call IS_ERR that is wrong.
