The driver status is set to flush when flush_decoder is called.
The order of STREAMOFF ioctl for OUTPUT and CAPTURE are randomly.
If flush_decoder is called in STREAMOFF for capture queue always,
leading to get NULL dst buffer when calling STREAMOFF for output
queue before capture queue.

Need to flush decoder when stream off no matter output or capture
queue is called firstly.
