Subject: [PATCH AUTOSEL 6.1 12/13] Bluetooth: mgmt: Fix limited discoverable off timeout

From: Frédéric Danis <frederic.danis@...labora.com>

[ Upstream commit 0bd1fb586235224048c726922db048d1bce6354a ]

LIMITED_DISCOVERABLE flag is not reset from Class of Device and
advertisement on limited discoverable timeout. This prevents to pass PTS
test GAP/DISC/LIMM/BV-02-C

Calling set_discoverable_sync as when the limited discovery is set
correctly update the Class of Device and advertisement.
