r600g: always clear query memory
According to the hw documentation, the driver needs to: - allocate 128 bits for each possible DB - clear the 128 bits for each possible DB - write 1 to bits 127 and 63 for upper DBs that don't exist on a particular asic Previously we were only doing these steps if the asic had less than the max possible DBs.
