fs/pipe: Convert to lockdep_cmp_fn
*_lock_nested() is fundamentally broken; lockdep needs to check lock
ordering, but we cannot device a total ordering on an unbounded number
of elements with only a few subclasses.
the replacement is to define lock ordering with a proper comparison
function.
fs/pipe.c was already doing everything correctly otherwise, nothing
much changes here.
