Brendan Shephard f91ffed95c rust: Return Option from page_align and ensure no usize overflow ...

Change `page_align()` to return `Option<usize>` to allow validation
of the provided `addr` value. This ensures that any value that is
within one `PAGE_SIZE` of `usize::MAX` will not panic, and instead
returns `None` to indicate overflow.
