[PATCH] KVM: x86: Add EOI exit bitmap handlers for Hyper-V SynIC vectors

[Wang Guangju <wangguangju@baidu.com>]

From: wangguangju <wangguangju@baidu.com>

Hyper-V SynIC vectors were added into EOI exit bitmap in func
synic_set_sint().But when the Windows VM VMEXIT due to
EXIT_REASON_EOI_INDUCED, there are no EOI exit bitmap handlers
for Hyper-V SynIC vectors.

This patch fix it.
