Yangtao Li 273c118fb0 f2fs: fix to set ipu policy ...

[ Upstream commit c5bf834833 ]

For LFS mode, it should update outplace and no need inplace update.
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.
