KVM: selftests: memslot_perf_test: Consolidate loop conditions in prepare_vm()

Browse Source 
There are two loops in prepare_vm(), which have different conditions.
'slot' is treated as meory slot index in the first loop, but index of
the host virtual address array in the second loop. It makes it a bit
hard to understand the code.

Change the usage of 'slot' in the second loop, to treat it as the
memory slot index either.

No functional change intended.
