hw/i386/pc: Defer smbios_set_defaults() to machine_done

Handling most of smbios data generation in the machine_done notifier is similar
to how the ARM virt machine handles it which also calls smbios_set_defaults()
there. The result is that all pc machines are freed from explicitly worrying
about smbios setup.
