Subject: [PATCH] f2fs: Fix build error while CONFIG_NLS=m

If CONFIG_F2FS_FS=y but CONFIG_NLS=m, building fails:

fs/f2fs/file.o: In function `f2fs_ioctl':
file.c:(.text+0xb86f): undefined reference to `utf16s_to_utf8s'
file.c:(.text+0xe651): undefined reference to `utf8s_to_utf16s'

Select CONFIG_NLS to fix this.
