greater than the buffer has room for data. Fix this by taking the

Once we start persistently storing the addresses of devices we want to
reconnect to we also need a way to reload them to the stack. Since we
don't have a connection object at this point the API cannot take that
as a parameter. Instead rename the function and have it take
bt_addr_le_t as a parameter.
The feature was also lacking proper reference counting for the
connection, which this patch now adds (the flag itself owns a
reference). The function is now also possible to call before bt_init()
so that if we load the stack with multiple devices the HCI doesn't get
bombarded with lots of scan enable/disable commands.

tx_fiber itself takes care of unrefing in case of failure. We need to

leave it alone in case of failure (when it's the original tx buffer).
