x86/hyperv: Fix definition of hv_ghcb_pg variable
The percpu variable hv_ghcb_pg is incorrectly defined. The __percpu qualifier should be associated with the union hv_ghcb * (i.e., a pointer), not with the target of the pointer. This distinction makes no difference to gcc and the generated code, but sparse correctly complains. Fix the definition in the interest of general correctness in addition to making sparse happy. No functional change.
