Remove array_size() calls and replace vmalloc() with vmalloc_array() to
simplify the code and maintain consistency with existing kmalloc_array()
usage.

vmalloc_array() is also optimized better, resulting in less instructions
being used [1].
Have you considered using sizeof(*...) where it makes sense?
I believe that sizeof(*...) should preferably not be mixed with this patch;
instead, it should be addressed in a separate, independent patch that
covers all relevant instances.

Additionally, I understand that not everyone prefers using sizeof(*...), as
it reduces readability.  What do you think, Andy?
