[Bluez] Monitor: Remove handle before assigning

From: Archie Pusaka <apusaka@chromium.org>

It is possible to have some handles not removed, for example the host
may decide not to wait for disconnection complete event when it is
suspending. In this case, when the peer device reconnected, we might
have two of the same handle assigned and create problem down the road.

This patch solves the issue by always removing any previous handles
when assigning a new handle if they are the same.

We might as well return if we find out there is a packet_conn_data,
that way we don't need to do 2 lookups in a row.

Are these changes really intentional? Or perhaps we don't want to
attempt to resolve the address since these are the event that would
assign them in the first place? In that case I had these fixed
separately with a proper patch description.

Do you mean to return the index, so we can immediately use the index
in the assign_handle function?

Yes, these are intentional. Otherwise, we would still print the
previous (faulty) address as the printing happens before we release
the handle.
Also, we print the (correct) address anyway immediately on the next line.
Do you still want this to be in a separate patch?

I think you can return the pointer directly:


conn = release_handle(handle);
if (conn)
   hci_devba(index, conn->src);
...
