[ Upstream commit ceaf1451990e3ea7fb50aebb5a149f57945f6e9f ]
Setting dir_cache_timeout to zero should disable the caching of directory contents. Currently, even when dir_cache_timeout is zero, some caching related functions are still invoked, which is unintended behavior.
Fix the issue by setting tcon->nohandlecache to true when dir_cache_timeout is zero, ensuring that directory handle caching is properly disabled.
