crypto: hisilicon/qm - add device status check when start fails

In function 'hisi_qm_resume', if the device fails to be started,
directly returning error code will cause the device to be unavailable.
However, the failure may be caused by device error, which will be
reported to the driver, and driver can reset and restart device.
Therefore, check device status instead of returning error code
directly. Returns 0 if device error has occurred, otherwise returns
error code.
