hw/core/machine-smp: Remove deprecated "parameter=0" SMP configurations
The "parameter=0" SMP configurations have been marked as deprecated
since v6.2.
For these cases, -smp currently returns the warning and adjusts the
zeroed parameters to 1 by default.
Remove the above compatibility logic in v9.0, and return error directly
if any -smp parameter is set as 0.
