Use this new state for Hyper-V initialization so that hyperv_pcpu_input_arg is allocated early enough.

The return value of the function is modified to u64. 2. Remove the d_info1 and d_info2 parameters from the function, keep the u64 type kernel_version parameter. 3. Rename the function to make it clearly a Hyper-V related function, and modify it to hv_generate_guest_id.
