hw/audio/marvell_88w8618: skip automatic zero-init of large array
The 'mv88w8618_audio_callback' 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 'buf' array will be fully initialized when reading data from
device memory.
