All this happens after riscv_cpu_realize(), meaning that we're already past riscv_cpu_validate_set_extensions() and, more important, riscv_cpu_disable_priv_spec_isa_exts(). This means that all extensions that needed to be disabled due to priv_spec mismatch are already disabled. Checking this again during riscv_isa_string_ext() is unneeded. Remove it. As a bonus, riscv_isa_string_ext() can now be used with the 'host' KVM-only CPU type since it doesn't have a env->priv_ver assigned and it would fail this check for no good reason.
