winverbs: convert RDMA address to network-byte order

winverbs: convert RDMA address to network-byte order

Change the winverbs interface to accept remote RDMA addresses in network
byte order.  This keeps it consistent with all other remote/wire data fields.

Unfortunately, this means that the remote address must be swizzled between
winverbs and the HCA libraries, which take the address in host order, but
the other fields in network order.  Longer term, the HCA libraries can provide
optimized interfaces for winverbs, like posting a single work request.

For now, to avoid compatibility issues later, define the winverbs interface
using what's most reasonable.  Update libibverbs accordingly.
