Subject: [PATCH] memusage.1: Use sizeof consistently

Use ``sizeof`` consistently through all the examples in the following
way:

- Use the name of the variable instead of its type as argument for
``sizeof``.

Rationale:
https://www.kernel.org/doc/html/v5.8/process/coding-style.html#allocating-memory
