From: Xiaojuan Yang <yangxiaoj...@loongson.cn>
In ipi_send function, it should not to set irq before
writing data to dest cpu iocsr space, as the irq will
trigger after data writing.
When call this function 'address_space_stl()', it will
trigger loongarch_ipi_writel(), the addr arg is 0x1008
('CORE_SET_OFF'), and qemu_irq_raise will be called in
this case.
