Bluetooth: SDP: Send resolved UUID data to user

After getting whole UUID response for SSA PDU request the user can be
informed about discovery results. Result data feeding the user is
splitted to logical record chunks if more than one record was found.
Every such portion represent unparsed SDP record prestripped from record
length. Each response record data passed to user starts from first raw
attributes data and the record response buffer's length tells exactly
about each record length. User UUID callback handler's return result
can drive delivery (dis)continuation of every such portion to the user.
