fuse: Allow fuse_fill_super_common() for submounts
Submounts have their own superblock, which needs to be initialized. However, they do not have a fuse_fs_context associated with them, and the root node's attributes should be taken from the mountpoint's node. Extend fuse_fill_super_common() to work for submounts by making the @ctx parameter optional, and by adding a @submount_finode parameter. (There is a plain "unsigned" in an existing code block that is being indented by this commit. Extend it to "unsigned int" so checkpatch does not complain.)
