f2fs: expose extension_list sysfs entry
This patch adds a sysfs entry 'extension_list' to support
query/add/del item in extension list.
Query:
cat /sys/fs/f2fs/<device>/extension_list
Add:
echo 'extension' > /sys/fs/f2fs/<device>/extension_list
Del:
echo '!extension' > /sys/fs/f2fs/<device>/extension_list
