mm profiling: Remove superfluous sentinel element from ctl_table

This commit is part of a greater effort to remove all empty elements at
the end of the ctl_table arrays (sentinels) which will reduce the
overall build time size of the kernel and run time memory bloat by ~64
bytes per sentinel (further information Link :
