commit 39307f8ee3539478c28e71b4909b5b028cce14b1 upstream.
[Please apply to 5.10-stable, 5.12-stable, and 5.13-stable.]
The casefolding feature is only supported when CONFIG_UNICODE is set.
This modifies the feature list f2fs presents under sysfs accordingly.
Fixes: 5aba54302a46 ("f2fs: include charset encoding information in the
superblock")
