KVM: x86: move all vcpu->arch.pio* setup in emulator_pio_in_out()
For now, this is basically an excuse to add back the void* argument to
the function, while removing some knowledge of vcpu->arch.pio* from
its callers. The WARN that vcpu->arch.pio.count is zero is also
extended to OUT operations.
The vcpu->arch.pio* fields still need to be filled even when the PIO is
handled in-kernel as __emulator_pio_in() is always followed by
complete_emulator_pio_in(). But after fixing that, it will be possible to
to only populate the vcpu->arch.pio* fields on userspace exits.
No functional change intended.
