Jonas Dreßler b439de9f7c Bluetooth: mgmt: Remove leftover queuing of power_off work 
[ Upstream commit fee054b757 ]

Queuing of power_off work was introduced in these functions with commits
8b064a3ad3 ("Bluetooth: Clean up HCI state when doing power off") and
c9910d0fb4 ("Bluetooth: Fix disconnecting connections in non-connected
states") in an effort to clean up state and do things like disconnecting
devices before actually powering off the device.

After that, commit a3172b7eb4 ("Bluetooth: Add timer to force power off")
introduced a timeout to ensure that the device actually got powered off,
even if some of the cleanup work would never complete.

This code later got refactored with commit cf75ad8b41 ("Bluetooth:
hci_sync: Convert MGMT_SET_POWERED"), which made powering off the device
synchronous and removed the need for initiating the power_off work from
other places. The timeout mentioned above got removed too, because we now
also made use of the command timeout during power on/off.

These days the power_off work still exists, but it only seems to only be
used for HCI_AUTO_OFF functionality, which is why we never noticed
those two leftover places where we queue power_off work. So let's remove
that code.

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.
