Commit a1b18df9a4848, broke virt_kvm_type() logic, which depends on
maxram_size, ram_size, ram_slots being parsed/set on machine instance
at the time accelerator (KVM) is initialized.

set_memory_options() part was already reverted by commit 2a7b18a3205b,
so revert remaining initialization of above machine fields to make
virt_kvm_type() work as it used to.

Oh I did not notice set_memory_options() change was already reverted.

Nit: Before configure_accelerators() call there is a comment stating
that configure_accelerators uses machine properties and must be called
after machine_set_property. Maybe we should add it also uses memory
properties and should be called after set_memory_options. This may avoid
other changes of the same style.

Thanks

Eric
