[PATCH v9 4/9] machine: Print CPU model name instead of CPU type

[Gavin Shan]

The names of supported CPU models instead of CPU types should be
printed when the user specified CPU type isn't supported, to be
consistent with the output from '-cpu ?'.

Correct the error messages to print CPU model names instead of CPU
type names.
