Here add illegal parameter check in kvm_vcpu_ioctl_interrupt() since this
function is called from user mode. Also interrupt inject is handled with
batch method, rather one by one.

---
v3 ... v4:
  1. change type of local variable vector with unsigned int rather than
     int, and use abs() macro.
  2. Remove last patch since kvm_vcpu_sync_intr() does not sync cached
     AVEC interrupt to SW CSR_ISR state.
  3. Replace kvm_set_sw_gcsr() with kvm_write_sw_gcsr() in patch 5,
     since kvm_set_sw_gcsr() is ORed cached ESTAT interrupt bits,
     kvm_write_sw_gcsr() is to overwrite the whole SW ESTAT register.
  4. Modify typo issue about title and log message in patch 5, replace
     GSTAT with ESTAT

v2 ... v3:
  1. Split patch 1 into two smaller patches, one is smaller bugfix patch
     with irq validility check in kvm_vcpu_ioctl_interrupt(), so that it
     is easy to porting to old kernel.

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.
