[media] v4l2-async: Use kmalloc_array() in v4l2_async_notifier_unregister()
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.
