bcachefs: fix overflow in fiemap
filefrag (and potentially other utilities that call fiemap) sometimes
pass ULONG_MAX as the length. fiemap_prep clamps excessively large
lengths - but the calculation of end can overflow if it occurs before
calling fiemap_prep. When this happens, filefrag assumes it has read to
the end and exits.
