f2fs: fix double free of unicode map

Browse Source 
[ Upstream commit 89ff6005039a878afac87889fee748fa3f957c3a ]

In case of retrying fill_super with skip_recovery,
s_encoding for casefold would not be loaded again even though it's
already been freed because it's not NULL.
Set NULL after free to prevent double freeing when unmount.
