selftests: kvm: fix overlapping addresses in memslot_perf_test
vm_create allocates memory and maps it close to GPA. This memory is separate from what is allocated in subsequent calls to vm_userspace_mem_region_add, so it is incorrect to pass the test memory size to vm_create_default. Just pass a small fixed amount of memory which can be used later for page table, otherwise GPAs are already allocated at MEM_GPA and the test aborts.
