    tools/libxl: libxl_set_memory_target: Fix compile error in backport
    
    013ee593ca04 the backport of "libxl: fix libxl_set_memory_target"
    was broken:
    
      libxl.c:5034:5: error: 'r' undeclared (first use in this function)
    
    This is because this old version of the function uses
    (inappropriately) rc for libxc error returns.
    
    Fix this by introducing `int r'.  We now use this in our backport,
    even though the rest of the function is incoherent about the use of
    rc.
