Just like the way we calculate next for pud and pmd, aka
round down and add size.

Also, do not do boundary-checking with 'next', and just pass 'end'
down to phys_pud_init() instead. Because the loop in phys_pud_init()
terminates at PTRS_PER_PUD and thus can handle a possibly bigger
'end' properly.
