KVM: x86: Fix PV IPIs for 32-bit KVM host
The recognition of the KVM_HC_SEND_IPI hypercall was unintentionally
wrapped in "#ifdef CONFIG_X86_64", causing 32-bit KVM hosts to reject
any and all PV IPI requests despite advertising the feature. This
results in all KVM paravirtualized guests hanging during SMP boot due
to IPIs never being delivered.
