KVM: selftests: Drop unused kvm_userspace_memory_region_find() helper

Browse Source 
Drop kvm_userspace_memory_region_find(), it's unused and a terrible API
(probably why it's unused).  If anything outside of kvm_util.c needs to
get at the memslot, userspace_mem_region_find() can be exposed to give
others full access to all memory region/slot information.
