    tools/libxl: Assert that libxl__ao_inprogress_gc() is not called with NULL
    
    libxl__ao_inprogress_gc() is hidden behind various macros used to
    construct local variables.  Assert() that NULL is not passed, to make
    such an error very obvious, rather than a plain segfault at 0.
    
    No functional change.
