ASoC: cros_ec_codec: fix uninitialized memory read
gcc points out a memory area that is copied to a device
but not initialized:
sound/soc/codecs/cros_ec_codec.c: In function 'i2s_rx_event':
arch/x86/include/asm/string_32.h:83:20: error: '*((void *)&p+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
83 | *((int *)to + 1) = *((int *)from + 1);
Initialize all the unused fields to zero.
Fixes: 727f1c71c780 ("ASoC: cros_ec_codec: refactor I2S RX")
