f2fs: xattr simplifications
Now that the xattr handler is passed to the xattr handler operations, we have access to the attribute name prefix, so simplify f2fs_xattr_generic_list. Also, f2fs_xattr_advise_list is only ever called for f2fs_xattr_advise_handler; there is no need to double check for that.
