ext4: Add sanity check to make_indexed_dir
(cherry picked from commit e6b8bc09ba2075cd91fbffefcd2778b1a00bd76f)
Make sure the rec_len field in the '..' entry is sane, lest we overrun
the directory block and cause a kernel oops on a purposefully
corrupted filesystem.
Thanks to Sami Liedes for reporting this bug.
