tipc: use destination length for copy string
Got below warning with gcc 8.2 compiler.
net/tipc/topsrv.c: In function ‘tipc_topsrv_start’:
net/tipc/topsrv.c:660:2: warning: ‘strncpy’ specified bound depends on the length of the source argument [-Wstringop-overflow=]
strncpy(srv->name, name, strlen(name) + 1);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
net/tipc/topsrv.c:660:27: note: length computed here
strncpy(srv->name, name, strlen(name) + 1);
^~~~~~~~~~~~
So change it to correct length and use strscpy.
