Jeff Fan f56379f361 UefiCpuPkg/DxeMpLib: Fix bug when getting target C-State from eax
AP will get target C-State from eax[7:4]. We do shift in ebx firstly before set
to eax. It will lead ebx is incorrect in the next time.

The fix is to set ebx to eax firstly and does shift in eax. Thus, ebx could keep
original value.
