[PULL 29/65] migration/rdma: Drop dead qemu_rdma_data_init() code for !@host_port

[Juan Quintela]

From: Markus Armbruster <arm...@redhat.com>

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.
