  Log:
  Sync with FreeBSD/1.103.   In the softupdates case for ffs_truncate() we
  use vinvalbuf() to invalidate pending io and dependencies.  However,
  vinvalbuf() rightfully does not call vnode_pager_setsize() for us.  We must
  do this here.  This could potentially have caused numerous kinds of bugs,
  but it was specifically causing msync() deadlocks because msync() was
  writing out pages that should not have been valid.
