hw/ufs/lu: skip automatic zero-init of large array
The 'ufs_emulate_scsi_cmd' method has a 4k byte array used for copying data from the device. Skip the automatic zero-init of this array to eliminate the performance overhead in the I/O hot path. The 'outbuf' array will be fully initialized when data is copied from the guest. Signed-off-by: Daniel P.
