fsnotify_detach_mark() calls fsnotify_destroy_inode_mark() or fsnotify_destroy_vfsmount_mark() to remove mark from object list. These two functions are however very similar and differ only in the lock they use to protect the object list of marks. Simplify the code by removing the indirection and removing mark from the object list in a common function.
