Fix 64KB blocksize in ext3 directories
With 64KB blocksize, a directory entry can have size 64KB which does not
fit into 16 bits we have for entry lenght. So we store 0xffff instead and
convert value when read from / written to disk. The patch also converts
some places to use ext3_next_entry() when we are changing them anyway.
