#733 readSize should always be zero in TrackCallback

[Sirisha Alla]

The issue is seen on changeset 4733 along with patch for #561.

In the TrackCallback() introduced as part of #561 hot standby feature, since dataBuffer is returned in the ioVector is always NULL, readSize needs to be set to zero.

This may be also applicable in the case of ArrivalCallback.
