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.
