nilfs2: fix disorder in cp count on error during deleting checkpoints
This fixes a bug that checkpoint count gets wrong on errors when
deleting a series of checkpoints.
The count error is persistent since the checkpoint count is stored on
disk. Some userland programs refer to the count via ioctl, and this
bugfix is needed to prevent malfunction of such programs.
