[PATCH] sysctl: fix sizeof argument to match variable name

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

Fix sizeof argument to be the same as the data variable name.
Probably a copy/paste error.
Mostly harmless since both variables are unsigned int.

Fixes kernel bugzilla #197371:
  Possible access to unintended variable in "kernel/sysctl.c" line 1339
