You dont really need to iterate in the list of protos there exist a
function that does that for you take a look at sdp_get_proto_port, btw
there exist a similar code in client/bluetooth.c

Currently you are not checking for L2CAP psm just RFCOMM channel so
the code bellow would never be used.

I would suggest not mixing gobex prefix with your helper functions, in
fact it is probably fine to just use obexfuse e.g. obexfuse_connect.
