Replace strncpy() with strscpy(), fixes the following warning:
In function 'bearer_name_validate',
inlined from 'tipc_enable_bearer' at net/tipc/bearer.c:246:7:
net/tipc/bearer.c:141:2: warning: 'strncpy' specified bound 32 equals
destination size [-Wstringop-truncation]
strncpy(name_copy, name, TIPC_MAX_BEARER_NAME);
