[PATCH] radix tree: remove unused variable

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

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.

Fixes: 3a08cd52c37c7 ("radix tree: Remove multiorder support")
