[PATCH 19/19] staging: wfx: remove false positive warning

[Jerome Pouiller]

From: JÃrÃme Pouiller <jerome.pouiller@xxxxxxxxxx>

When a station is removed, the driver check that all the Tx frames were
correctly sent. However, the station can be removed before all the Tx
frames were acknowledged and a false positive warning can be emitted.

The previous commit has added a trace when driver received an
acknowledge for a non-existent station. It appear that these events
are perfectly correlated and there is no leak.

Now, the subject is perfectly understood. Remove the warning. Just keep
a debug trace in case we have any doubt in the future.

In the past, the subject has already been discussed here:
