ASoC: Use kcalloc() instead of kzalloc()

Merge series from Qianfeng Rong <rongqianfeng@vivo.com>:

Replace devm_kzalloc() with devm_kcalloc() in sound/soc.  As noted in the
kernel documentation [1], open-coded multiplication in allocator arguments
is discouraged because it can lead to integer overflow.

Using devm_kcalloc() provides built-in overflow protection, making the
memory allocation safer when calculating the allocation size compared
to explicit multiplication.
