dm: get vcpu num from hypervisor when create VM

Browse Source 
Now, we pre-define VM configuration statically in HV. So HV can create
vcpus instead of DM when VM create.

This patch get the created vcpu_num from HV. vm_create_vcpu can be
removed later if kernel can get vcpu_num correctly without
IC_CREATE_VCPU ioctl.

v4: Keep vm_create_vcpu in DM for compatbility. We might remove it when
kernel is ready.
