Subject: [PATCH] radix tree: remove unused variable

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.
