crypto: qat - fix problem with coalescing enable logic

Fixed issue reported by Dan Carpenter

410          if (adf_get_cfg_int(accel_dev, "Accelerator0",
411				 ADF_ETRMGR_COALESCING_ENABLED_FORMAT,
412                              bank_num, &coalesc_enabled) && coalesc_enabled)
This condition is reversed, so it only enables coalescing on error.
