qemu_rdma_resolve_host() and qemu_rdma_dest_init() try addresses until
they find on that works. If none works, they return the first Error
set by qemu_rdma_broken_ipv6_kernel(), or else return a generic one.
qemu_rdma_broken_ipv6_kernel() neglects to set an Error when
ibv_open_device() fails. If a later address fails differently, we use
that Error instead, or else the generic one. Harmless enough, but
needs fixing all the same.
