[ Upstream commit 355333a217541916576351446b5832fec7930566 ]
Commit 66307ca04057 ("ath11k: fix mgmt_tx_wmi cmd sent to FW for
deleted vdev") wants both of below two conditions are true before
sending management frames:
1: ar->allocated_vdev_map & (1LL << arvif->vdev_id)
2: arvif->is_started
Actually the second one is not necessary because with the first one
we can make sure the vdev is present.
Also use ar->conf_mutex to synchronize vdev delete and mgmt. TX.
This issue is found in case of Passpoint scenario where ath11k
needs to send action frames before vdev is started.
Fix it by removing the second condition.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
