[ovs-dev] [PATCH] ofp-util: Use correct error for indirect group with more than one bucket.

OpenFlow 1.5 says:

    If the group-mod request specifies more than one bucket for a group of
    type Indirect, the switch must refuse to add the group entry and must
    send an ofp_error_msg with OFPET_GROUP_MOD_FAILED type and

Older versions don't specify a particular error for this case, so we might
as well use it for older OpenFlow also.
