  Log:
   - Add an interlock argument to BUF_LOCK and BUF_TIMELOCK.
   - Remove the buftimelock mutex and acquire the buf's interlock to protect
     these fields instead.
   - Hold the vnode interlock while locking bufs on the clean/dirty queues.
     This reduces some cases from one BUF_LOCK with a LK_NOWAIT and another
     BUF_LOCK with a LK_TIMEFAIL to a single lock.
