[PATCH] lib: radix_tree: Fix error in docs about locks

[Adam Barth]

This text refers to the "first 7 functions", which was correct when
written but became incorrect when Johannes Weiner added another function
to the list in 139e561660fe ("lib: radix_tree: tree node interface").

Change the text to correctly refer to the first 8 functions.
