Commit 189829399070 ("xen-block: Use specific blockdev driver")
introduced a new error path, without taking care of allocated
resources.
So only allocate the qdicts after the error check, and free both
`filename` and `driver` when we are about to return and thus taking
care of both success and error path.
Coverity only spotted the leak of qdicts (*_layer variables).
