commit c89a6e7878e630718cce0af940e9c070c132ce30
Author: Jim Fehlig <jfehlig@suse.com>

    libxl: use init and dispose functions with libxl_physinfo
    
    The typical pattern when calling libxl functions that populate a
    structure is
    
      libxl_foo foo;
      libxl_foo_init(&foo);
      libxl_get_foo(ctx, &foo);
      ...
      libxl_foo_dispose(&foo);
    
    Fix several instances of libxl_physinfo missing the init and
    dispose calls.
