[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.
