crypto: hisilicon/qm - re-enable communicate interrupt before notifying PF 



After the device is reset, the VF needs to re-enable communication
interrupt before the VF sends restart complete message to the PF.
If the interrupt is re-enabled after the VF notifies the PF, the PF
may fail to send messages to the VF after receiving VF's restart
complete message.
