Stephen Sun 48908b1c5a Fix issue: exception occurred during chassis object being destroyed () 
The following error message is observed during chassis object being destroyed

"Exception ignored in: <function Chassis.__del__ at 0x7fd22165cd08>
Traceback (most recent call last):
  File "/usr/local/lib/python3.7/dist-packages/sonic_platform/chassis.py", line 83, in __del__
ImportError: sys.meta_path is None, Python is likely shutting down
The chassis tries to import deinitialize_sdk_handle during being destroyed for the purpose of releasing the sdk_handle.
However, importing another module during shutting down can cause the error because some of the fundamental infrastructures are no longer available."

This error occurs when a chassis object is created and then destroyed in the Python shell.

- How I did it
To fix it, record the deinitialize_sdk_handle in the chassis object when sdk_handle is being initialized and call the deinitialize handler when the chassis object is being destroyed

- How to verify it
Manually test.
