[Xen-devel] [PATCH 12/28] libxl: Use libxl__device_model_xs_path in libxl__spawn_qdisk_backend

Rather than open-coding the answer.  We are going to change this path.

No functional change (other than to very unlikely error paths).

v6: Broken out from a portmanteau patch which was in v5, and fixed.
