page-writeback: fix the calculation of the oldest_jif in wb_kupdate()
wb_kupdate() function has a bug on linux-2.6.30-rc5. This bug causes generic_sync_sb_inodes() to start to write inodes back much earlier than our expectations because it miscalculates oldest_jif in wb_kupdate(). This bug was introduced in 704503d836042d4a4c7685b7036e7de0418fbc0f ('mm: fix proc_dointvec_userhz_jiffies "breakage"').
