[PATCH 20/52] migration/rdma: Drop dead qemu_rdma_data_init() code for !@host_port

[Markus Armbruster]

qemu_rdma_data_init() neglects to set an Error when it fails because
@host_port is null.  Fortunately, no caller passes null, so this is
merely a latent bug.  Drop the flawed code handling null argument.
