KVM: s390: sida: sort out physical vs virtual pointers usage
All callers of the sida_origin() macro actually expected a virtual
address, so rename it to sida_addr() and hand out a virtual address.
At some places, the macro wasn't used, potentially creating problems
if the sida size ever becomes nonzero (not currently the case), so let's
start using it everywhere now while at it.
