brcompat: Remove requirement that that no datapaths exist at load time.

We previously required that brcompat_mod be loaded before any datapaths
were created, because creation and destruction of datapaths and ports
differed when brcompat_mod was loaded, but the latter is no longer the
case so there is no reason for the former anymore.
