Dynamic allocating vcpu state structure according to smp value to be more precise and safe. Previously it will alloccate array of fixed size HAX_MAX_VCPU. This is achieved by using g_new0 to dynamic allocate the array. The allocated size is obtained from smp.max_cpus in MachineState. Also, the size is compared with HAX_MAX_VCPU when creating the vm. The reason for choosing dynamic array over linked list is because the status is visited by index all the time. This will lead to QEMU checking whether the smp value is larger than the HAX_MAX_VCPU when creating vm, if larger, the process will terminate, otherwise it will allocate array of size smp to store the status. V2: Check max_cpus before open vm.
