  Log:
  Eliminate a deadlock when creating snapshots.  Blocking vn_start_write() must
  be called without any vnode locks held.  Remove calls to vn_start_write() and
  vn_finished_write() in vnode_pager_putpages() and add these calls before the
  vnode lock is obtained to most of the callers that don't already have them.
