cifs: is_network_name_deleted should return a bool
Currently, is_network_name_deleted and it's implementations do not return anything if the network name did get deleted. So the function doesn't fully achieve what it advertizes. Changed the function to return a bool instead. It will now return true if the error returned is STATUS_NETWORK_NAME_DELETED and the share (tree id) was found to be connected. It returns false otherwise. Signed-off-by: Shyam Prasad N <sprasad@microsoft.com> Acked-by: Paulo Alcantara (SUSE) <pc@manguebit.com> Signed-off-by: Steve French <stfrench@microsoft.com>
