[PATCH] selftests: kvm: make allocation of extra memory take effect

[Zhenzhong Duan]

The extra memory pages is missed to be allocated during VM creating.
perf_test_util and kvm_page_table_test use it to alloc extra memory
currently.

Fix it by adding extra_mem_pages to the total memory calculation before
allocate.
