[PATCH] exec: Remove the duplicated check in parse_cpu_option()

[Gavin Shan]

The @cpu_option shouldn't be NULL, otherwise assertion from g_strsplit()
should be raised as below message indicates. So it's meaningless to validate
@model_pices[0] in parse_cpu_option() as it shouldn't be NULL either.

   qemu-system-aarch64: GLib: g_strsplit: assertion 'string != NULL' failed

This just removes the check and unused message.
