tipc: Simplify prohibition of listen and accept for connectionless sockets
Modifies the proto_ops structure used by TIPC DGRAM and RDM sockets
so that calls to listen() and accept() are handled by existing kernel
"unsupported operation" routines, and eliminates the related checks
in the listen and accept routines used by SEQPACKET and STREAM sockets
that are no longer needed.
