KVM: selftests: memslot_perf_test: Use data->nslots in prepare_vm()

Browse Source 
In prepare_vm(), 'data->nslots' is assigned with 'max_mem_slots - 1'
at the beginning, meaning they are interchangeable.

Use 'data->nslots' isntead of 'max_mem_slots - 1'. With this, it
becomes easier to move the logic of probing number of slots into
upper layer in subsequent patches.

No functional change intended.
