Summary
wifi: iwlwifi: read txq->read_ptr under lock
Details

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: read txq->read_ptr under lock

If we read txq->readptr without lock, we can read the same value twice, then obtain the lock, and reclaim from there to two different places, but crucially reclaim the same entry twice, resulting in the WARNONCE() a little later. Fix that by reading txq->read_ptr under lock.
