ste_dma40: Use kmalloc_array() in d40_hw_detect_init() 



A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".

This issue was detected also by using the Coccinelle software.
