[Devel] [PATCH RH7] sysctl: remove unused

[Pavel Tikhomirov]

After patch "bc: Rip old network buffers and sockets accounting" which
is merged into commit 054db2512a17 ("Initial patch commit + compilation
fixes") we do not use sysctl_tcp_max_tw_buckets_ub and
sysctl_tcp_max_tw_kmem_fraction.

We do not have check_area_access_ve the only place where
ve_area_access_check have been used so we do not need a sysctl.
