hw/audio/gus: skip automatic zero-init of large array
The 'GUS_read_DMA' method has a 4k byte array used for copying data between the audio backend and device. Skip the automatic zero-init of this array to eliminate the performance overhead in the I/O hot path. The 'tmpbuf' array will be fully initialized when reading data from device memory.
