Commit Message

  This is part of the effort to remove the end element (sentinel) from the
ctl_table arrays. Now that all the callers to register_net_sysctl are
actual arrays, we replace SIZE_MAX with ARRAY_SIZE of the table.

Stopping condition continues to be based on both size and procname null
test. This sets things up for when the sentinel element is actually
removed: Before removing sentinel the stopping criteria will be the last
null element. When the sentinel is removed then the (correct) size will
take over.
