[PATCH 5/8] sysctl: Remove superfluous empty allocations from sysctl internals

[Joel Granados via B4 Relay]

From: Joel Granados <j.granados@xxxxxxxxxxx>

Now that the sentinels have been removed from ctl_table arrays, there is
no need to artificially append empty ctl_table elements at ctl_table
registration. Remove superfluous empty allocation from new_dir and
new_links.
