Szymon Janc 082f2300cf Bluetooth: Fix connection if directed advertising and privacy is used 
Local random address needs to be updated before creating connection if
RPA from LE Direct Advertising Report was resolved in host. Otherwise
remote device might ignore connection request due to address mismatch.

This was affecting following qualification test cases:
GAP/CONN/SCEP/BV-03-C, GAP/CONN/GCEP/BV-05-C, GAP/CONN/DCEP/BV-05-C

README 

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.
