    page_alloc: fix MISRA C 2012 Rule 8.7 violation
    
    The variables page_offlined_list and page_broken_list are referenced only
    in page_alloc.c.
    Change their linkage from external to internal by adding the storage-class
    specifier static to their definitions.
    
    This patch also aims to resolve indirectly a MISRA C 2012 Rule 8.4 violation
    warning.
