6.4-stable review patch. If anyone has any objections, please let me know.

From: Arnd Bergmann arnd@arndb.de
commit d59070d1076ec5114edb67c87658aeb1d691d381 upstream.
Recent versions of clang warn about an unused variable, though older versions saw the 'slot++' as a use and did not warn:
radix-tree.c:1136:50: error: parameter 'slot' set but not used [-Werror,-Wunused-but-set-parameter]
It's clearly not needed any more, so just remove it.
