[Intel-wired-lan] [PATCH] ice: parser: use array_size() for table allocation

[Weimin Xiong]

Use array_size() when calculating the parser table allocation size so an
overflow in the firmware-provided item dimensions is detected before
allocation. Include the overflow helpers explicitly instead of relying on
an indirect include.
