in vfs_detach(). vfs_done may free global filesystem's resources, typically those allocated in respective filesystem's init function. Needed so those filesystems which went in via LKM have a chance to clean after themselves before unloading. This fixes random panics when LKM for filesystem using pools was loaded and unloaded several times. For each leaf filesystem, add appropriate vfs_done routine.
