Daniel Leung c38634fa33 kernel: mmu: fix assigning unaligned addr to page frame 
In do_page_fault(), the incoming page fault address is not
aligned, and it was unconditionally assigned to the page
frame virtual address field. If the backing store simply
returns the virtual address without processing in
k_mem_paging_backing_store_location_get(), this unaligned
address will be passed to arch_mem_page_out(). On x86,
it is further passed to range_map() which asserts if
the physical address is not page aligned. So align
the address to page size before assigning it to the page
frame virtual address field.
