w/ below change [1], f2fs will enable lookup_mode=perf by default, it will change f2fs dirent lookup method from linear based lookup to hash based lookup.
So that, f2fs will ignore sb.s_encoding_flags by default, which is not compatible w/ f2fs/012 testcase, in where it will control lookup method by configuring this flag w/ fsck.f2fs. To avoid failure of f2fs/012, let's check whether f2fs has supported "lookup_mode=auto" mount option, mount w/ the option if it can, otherwise, don't.
