  MFC: 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.
