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
