华为部分设备录屏不可用

**描述问题bug**

部分设备录屏后只在在手机里生成一个0B的MP4文件，尝试pull至pc端时会报未开始录制（不过这个报错应该是由于录制功能本身有问题）

（在这里粘贴traceback或其他报错信息）

AirtestError: 'start_recording first'

**复现步骤**
0.使用用华为畅想9plus或者华为麦芒7
1.命令行里随便带recording参数运行一个脚本
2.或者ide里运行下面的函数
def RecordTest():
oDevice = device()
oDevice.start_recording(max_time=1800, bit_rate=None, vertical=False)
sleep(2)
oDevice.stop_recording(is_interrupted=False)

**python 版本:** `python2.7`

**airtest 版本:** `1.0.24`

adb版本1.0.40

**设备:**
- 型号: 华为畅想9plus、华为麦芒7
- 系统: 8.2

**其他相关环境信息**
win 10 、ubuntu16、任何运行中环境都这样
相同环境下其他大部分手机录屏正常
