David Woodhouse 6f7997e004 hw/xen: clean up xen_block_find_free_vdev() to avoid Coverity false positive 
Coverity couldn't see that nr_existing was always going to be zero when
qemu_xen_xs_directory() returned NULL in the ENOENT case (CID 1523906).

Perhaps more to the point, neither could Peter at first glance. Improve
the code to hopefully make it clearer to Coverity and human reviewers
alike.
