    kernel -- ffs: Softdep lock and assorted fixes
    * Remove interlocked_sleep; we can just use lksleep directly
    * sema_get no longer eats the interlock passed in; all of its
      callers were retaking the lock eventually or immediately.
    * softdep was setting up a callout to wake itself in request_cleanup.
      Switch to directly using timeout in lksleep for this purpose.
    * Do not access inodedep structure outside of softdep lock in
      softdep_update_inodeblock for buffer field.
    * Remove prio field from semaphores; they were unused and the DFly
      tsleep routines do not respect priority anyway.
    * Do not release softdep lock before panic()ing
