When using LFS mode for small-volume devices, IPU will not be used, and the OPU writing method is actually used, but F2FS_IPU_FORCE can be read from the ipu_policy node, which is different from the actual situation. And remount to lfs mode should be disallowed when f2fs ipu is enabled, let's fix it.
