tracing: make tracing_init_dentry() returns an integer instead of a d_entry pointer
Current tracing_init_dentry() return a d_entry pointer, while is not necessary. This function returns NULL on success or error on failure, which means there is no valid d_entry pointer return. Let's return 0 on success and negative value for error.
