Janis Schoetterl-Glausch 7faa543df1 KVM: s390: gaccess: Refactor access address range check
Do not round down the first address to the page boundary, just translate
it normally, which gives the value we care about in the first place.
Given this, translating a single address is just the special case of
translating a range spanning a single page.

Make the output optional, so the function can be used to just check a
range.
