KVM: SEV-ES: clean up kvm_sev_es_ins/outs

A few very small cleanups to the functions, smushed together because
the patch is already very small like this:

- inline emulator_pio_in_emulated and emulator_pio_out_emulated,
  since we already have the vCPU

- remove the data argument and pull setting vcpu->arch.sev_pio_data into
  the caller

- remove unnecessary clearing of vcpu->arch.pio.count when
  emulation is done by the kernel (and therefore vcpu->arch.pio.count
  is already clear on exit from emulator_pio_in and emulator_pio_out).

No functional change intended.
