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