Luiz Augusto von Dentz 98f66ea456 Bluetooth: hci_conn: Fix UAF Write in __hci_acl_create_connection_sync 
[ Upstream commit 5f641f03ab ]

This fixes the UAF on __hci_acl_create_connection_sync caused by
connection abortion, it uses the same logic as to LE_LINK which uses
hci_cmd_sync_cancel to prevent the callback to run if the connection is
abort prematurely.

README

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.
