Szymon Janc f58ef38ef1 Bluetooth: Fix connection if directed advertising and privacy is used 
commit 082f2300cf upstream.

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
