KVM: s390: Add some useful mask macros

Add _{SEGMENT,REGION3}_FR_MASK, similar to _{SEGMENT,REGION3}_MASK, but
working on gfn/pfn instead of addresses. Use them in gaccess.c instead
of using the normal masks plus gpa_to_gfn().

Also add _PAGES_PER_{SEGMENT,REGION3} to make future code more readable.
