list-buffers-noselect: `when' should be `and'

[Drew Adams]

`when' should be `and' in this code, for clarity. I don't think this
has an effect on functioning, but `when' should generally not be used
when its value is important, as in this case. Here, the return value
is an argument to function `buffer-list'.

(dolist (buffer (or buffer-list
                          (buffer-list
                           (when Buffer-menu-use-frame-buffer-list
                             (selected-frame)))))
  ...)
