block/ssh: fix possible segmentation fault when .desc is not null-terminated
This patch prevents a possible segmentation fault when .desc members are checked
against NULL.
The ssh_runtime_opts was added by commit
8a6a80896d6af03b8ee0c17cdf37219eca2588a7 ("block/ssh: Use QemuOpts for runtime
options").
This fix was inspired by
http://lists.nongnu.org/archive/html/qemu-devel/2018-01/msg00883.html.
