target/arm/monitor: query-cpu-model-expansion crashed qemu when using machine type none
Commit e19afd566781 mentioned that target-arm only supports queryable
cpu models 'max', 'host', and the current type when KVM is in use.
The logic works well until using machine type none.
For machine type none, cpu_type will be null if cpu option is not
set by command line, strlen(cpu_type) will terminate process.
So We add a check above it.
This won't affect i386 and s390x since they do not use current_cpu.
