[PATCH v1 3/7] media: chips-media: wave5: Fix not to be closed

[Jackson.lee]

From: Jackson Lee <jackson.lee@xxxxxxxxxxxxxxx>

The current code was to wait interrupt if queue or report queue is not 0,
but since applying the performance patch, input and output is not any
more synchronized.
So even if queue count is not 0, an interrupt could not be triggered.

Fixes: 15a4f7492acc ("media: chips-media: wave5: Improve performance of decoder")
