Here make interrupt status acquire interface simpler, add new interface
kvm_vcpu_sync_intr() to sync pending interrupt to software ESTAT
register, and remove expensive vcpu_load() and vcpu_put() function call.

Also interrupt inject is handled with batch method, rather one by one.

---
v1 ... v2:
  1. Add irq validility check in function kvm_vcpu_ioctl_interrupt().
  2. Add valid bit check when set ESTAT CSR register.
  3. Merge two patches about interrupt clear and set with batch method into
     one.
