mm/memory-failure: replace magic number 3 with GET_PAGE_MAX_RETRY_NUM

Replace the hardcoded magic number 3 in get_any_page() with the existing
GET_PAGE_MAX_RETRY_NUM macro for code consistency and maintainability.

This change has no functional impact, only improves code readability and
unifies the retry limit configuration.
