IPoIB: Add high DMA feature flag

All current InfiniBand devices can handle all DMA addresses, and it's hard to imagine anyone would be silly enough to build a new device that couldn't. Therefore, enable the NETIF_F_HIGHDMA feature for IPoIB. This has no effect for no, but is needed when we enable gather/scatter support and checksum stateless offloads.
