[ Upstream commit 4b387906b1c3692bb790388c335515c0cf098a23 ] When a queue is reserved for aggregation, the queue id is assigned to the tid_data. This is fine since iwl_mvm_sta_tx_agg_oper() takes care of allocating the queue before actual tx starts. When the reservation is cancelled (e.g. when the AP declined the aggregation request) the tid_data is not cleared. As a result, following tx for this tid was trying to use an unallocated queue. Fix this by setting the txq_id for the tid to invalid when unreserving the queue.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
