Minor refactor of the code in ExecScanExtended()

Hi,

The current code:

      if (!qual && !projInfo)

      {

            ResetExprContext(econtext);

            return ExecScanFetch(node, epqstate, accessMtd, recheckMtd);

      }

      ResetExprContext(econtext);

The following format might be simpler:

      ResetExprContext(econtext);

      if (!qual && !projInfo)

            return ExecScanFetch(node, epqstate, accessMtd, recheckMtd);

Attach a patch to do this.
