[PATCH -next] x86/hyperv: Fix build error while CONFIG_PARAVIRT=n

[YueHaibing]

while CONFIG_PARAVIRT=n, building fails:

arch/x86/kernel/cpu/mshyperv.c: In function ms_hyperv_init_platform:
arch/x86/kernel/cpu/mshyperv.c:219:2: error: pv_info undeclared (first use in this function); did you mean pr_info?
  pv_info.name = "Hyper-V";
  ^~~~~~~

Wrap it into a #ifdef to fix this.

Fixes: 628270ef628a ("x86/hyperv: Set pv_info.name to "Hyper-V"")
