[PATCH v2 1/5] xen/common: page_alloc: Fix MISRA C 2012 Rule 8.7 violation

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

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.

Also, this patch aims to resolve indirectly a MISRA C 2012 Rule 8.4 violation
warning.

  indirectly a MISRA C 2012 Rule 8.4 violation warning."
