Fix UAF in sdp_discovery.cc
It is possible with modifications to a client to open two connections
against the same SDP discovery database. If this happens, it becomes
possible to reference a freed instance of the discovery database in the
second connection once the first one is closed.
To guard against this, check during discovery if a database has already
been allocated, and abort iff it has.
Also, add a null check to process_service_search_attr_rsp to guard
against unchecked calls to the SDP discovery database.
