IB/core: Introduce and use rdma_create_user_ah
Introduce rdma_create_user_ah API which allows passing udata to provider driver and additionally which resolves DMAC for RoCE. ib_resolve_eth_dmac() resolves destination mac address for unicast, multicast, link local ipv4 mapped ipv6 and ipv6 destination gid entry. This allows all RoCE provider drivers to avoid duplicating such code. Such change brings consistency where IB core always resolves dmac and pass it to RoCE provider drivers for user and kernel consumers, with this ah_attr->roce.dmac is always an input field for provider drivers. This uniformity avoids exporting ib_resolve_eth_dmac symbol to providers or other modules. Therefore its removed as exported symbol at later in the patch series. Now uverbs and umad both makes use of rdma_create_user_ah API which fixes the issue where umad has invalid DMAC for address.
