i965: Write TIMESTAMP query values into the first buffer element.

Browse Source 
For timestamp queries, we just write a single value to a BO.  The
natural place to write that is element 0, so we should do that.

Previously, we wrote it into element 1 (the second slot) leaving
element 0 filled with garbage.
