[Bluetooth]: Track page scan repetition mode changes
The HCI page scan repetition mode change event contains the actual page scan repetition mode for the remote device. It is the same value that is received from an inquiry response and it can be used to make further reconnections faster. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: David S.
