Fix can_map_at_level() to ensure all memory areas related the pager
pageable virtual memory are mapped with small pages. This change
fixes an issue found when the pager physical RAM ends on a section
boundary (e.g. 512MB or 2MB on LPAE case) making the virtual memory
mapping above that boundary to be prepared with pgdir or wider MMU tables
while pager implementation expects 4kB page MMU tables.
