    ext2fs: fix pager use-after-free
    
    Previously, pagers had no reference for being part of a node, only for
    having a send right made for them.  Hence we sometimes saw
    use-after-free errors if the kernel did give up that send right,
    typically while deleting files.  Keep a weak reference as long as the
    pager is referenced by a node.
    
    * ext2fs/pager.c (pager_clear_user_data): Assert that 'pager' has been
    NULLed.
    (pager_dropweak): Drop the weak reference and NULL 'pager'.
    (diskfs_get_filemap): Simplify.  Acquire a weak reference.
