mds: fix MDSTableClient ack double journaling

Do not journal ack unless the tid is registered in the LogSegment.  Once
we journal it, we remove it from the LogSegment list, and once it's
journaled, we remove the pending_commit[tid] entry.

This fixes a bug where the mds got two acks, journaled both of them, and
crashed in the completion for the second because pending_commit[tid] was
gone.  The second ack should have been ignored.
