[ovs-dev] [PATCH] openvswitch: fix odd_ptr_err.cocci warnings

[kbuild test robot]

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.
