Here is to remove some unnecessary parameter checking when injecting
MSI interrupt, include MSI level parameter and vcpu::arch::dmsintc_state
NULL pointer etc.
---
v1 ... v2:
  1. Remove function dmsintc_deliver_msi_to_vcpu() and inline it in
     dmsintc_set_irq().

  2. Keep return value with -1 rather than -EINVAL when level == 0
     in kvm_set_msi(). Return value with 0 is one option also, now keep
     similar with other architectures, will modify this in future when the
     final solution is made.
