radix tree: remove unused variable 

stable inclusion
from stable-v5.10.193
commit 851f686ed0f5c129d5e764e7532ee4475fcfdec6
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I9399M

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=851f686ed0f5c129d5e764e7532ee4475fcfdec6

--------------------------------

commit d59070d1 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.
