While the presence of the '--bundle' option implicitly added the
OpenFlow 1.4 to the allowed protocols, it failed to remove OpenFlow
1.0 from the allowed protocols. This is changed so that '--bundle'
option now also implicitly removes versions lesser than 1.4 from the
allowed protocols. This has no behavioral difference when ovs-ofctl
is paired with OVS that supports OpenFlow 1.4, as the greatest common
version is negotiated, but prevents negotiation of OpenFlow 1.0 when
OVS does not support OpenFlow 1.4.
