[PATCH 2/3] ASoC: simple-card: Use devm_kcalloc() in asoc_simple_card_probe()

Multiplications for the size determination of memory allocations
indicated that array data structures should be processed.
Thus use the corresponding function "devm_kcalloc".

This issue was detected by using the Coccinelle software.
