kernel/sysctl.c: fix sizeof argument to match variable name
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
