[PATCH 1/4] GPU-DRM-TILCDC: Use kmalloc_array() in kfree_table_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 by using the Coccinelle software.
