bs.el: Use the right buffer context to compute the mode name

* lisp/bs.el (bs--get-mode-name): The function is already called
with the correct buffer as current-buffer; and anyway, START-BUFFER
is usually the wrong one to pass to `format-mode-line'.  This fixes
a bug introduced in 48d33090d0 and c2699583be (back in 2008-01-04).
