x86/hyperv: Improve code for referencing hyperv_pcpu_input_arg
Several places in code for Hyper-V reference the
per-CPU variable hyperv_pcpu_input_arg. Older code uses a multi-line
sequence to reference the variable, and usually includes a cast.
Newer code does a much simpler direct assignment. The latter is
preferable as the complexity of the older code is unnecessary.
Update older code to use the simpler direct assignment.
