page_pool: constify some read-only function arguments
There are several functions taking pointers to data they don't modify. This includes statistics fetching, page and page_pool parameters, etc. Constify the pointers, so that call sites will be able to pass const pointers as well. No functional changes, no visible changes in functions sizes.
