x86/mm: Make vmemmap and vmalloc base address constants unsigned long

x86/mm: Make vmemmap and vmalloc base address constants unsigned long

Commits 291474bc73 ("x86/mm: Initialize vmemmap_base at boot-time") and
f09177c1a4 ("x86/mm: Adjust vmalloc base and size at boot-time") lost the
type information for __VMALLOC_BASE_L4, __VMALLOC_BASE_L5,
__VMEMMAP_BASE_L4 and __VMEMMAP_BASE_L5 constants.

Declare them explicitly unsigned long again.
