We set hdev->cur_adv_instance in the adv param MGMT request to allow the callback to the hci param request to set the tx power to the correct instance. Now that the callbacks use the advertising handle from the hci request (as they should), this workaround is no longer necessary. Furthermore, this change resolves a race condition that is more prevalent when using the extended advertising MGMT calls - if hdev->cur_adv_instance is set in the params request, then when the data request is called, we believe our new instance is already active. This treats it as an update and immediately schedules the instance with the controller, which has a potential race with the software rotation adv update. By not setting hdev->cur_adv_instance too early, the new instance is queued as it should be, to be used when the rotation comes around again. This change is tested on harrison peak to confirm that it resolves the race condition on registration, and that there is no regression in single- and multi-advertising automated tests.

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.
