commit 1ea1cd11c72d1405a6b98440a9d5ea82dfa07166 upstream.
When directory's last extent has more that one block and its length is
not multiple of a block side, the code wrongly decided to move to the
next extent instead of processing the last partial block. This led to
directory corruption. Fix the rounding issue.
