tipc: Enhance error checking of published names
Consolidates validation of scope and name sequence range values into a single routine where it applies both to local name publications and to name publications issued by other nodes in the network. This change means that the scope value for non-local publications is now validated and the name sequence range for local publications is now validated only once. Additionally, a publication attempt that fails validation now creates an entry in the system log file only if debugging capabilities have been enabled; this prevents the system log from being cluttered up with messages caused by a defective application or network node.
