Both of these initialization steps need to know what the maximum possible I/O size will be, and when we gain support for indirect segment I/Os we won't know that value until we reach xbd_connect. Since none of this data is used before xbd_connect completes, moving the initialization is harmless. This commit should not result in any functional changes. END
