ASoC: core: fix possible ZERO_SIZE_PTR pointer dereferencing error. Since we cannot make sure the 'params->num_regs' will always be none zero here, and then if it equals to zero, the kmemdup() will return ZERO_SIZE_PTR, which equals to ((void *)16). So this patch fix this with just doing the zero check before calling kmemdup().
