[PATCH AUTOSEL 6.6 01/19] ASoC: SOF: topology: Use krealloc_array() to replace krealloc()

[Sasha Levin]

From: Zhang Heng <zhangheng@xxxxxxxxxx>

[ Upstream commit a05143a8f713d9ae6abc41141dac52c66fca8b06 ]

Use krealloc_array() to replace krealloc() with multiplication.
krealloc_array() has multiply overflow check, which will be safer.
