LU-14768 e2fsck: merge casefolded dir lists after thread finish

This is missed and should be done after threads finish.

Original commit:
18538b27 ("LU-8465 e2fsck: merge encrypted dir lists after thread finish")
Upstream is now using e2fsck_struct->casefolded_dirs instead of
encrypted_dirs.

Only for the correctness of pfsck, we won't use casefolded feature on
ldiskfs.
