  Log:
   - 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
     flushing pages that should not have been valid.
