uek-rpm: disable CONFIG_NUMA_BALANCING_DEFAULT_ENABLED

Orabug: 26798697

This commit disables automatic NUMA balancing by default.
Numerous customers have experienced high iowait due to
oracle db processes sitting in D state on wait_on_page_bit()
because memory pages containing data segment of the oracle
db processes are migrated aggressively across NUMA nodes.

The solution is to disable automatic NUMA balancing by
default until NUMA balancing algorithm is modified to
address this issue.  Note that NUMA balancing may
still be enabled with this change by setting
kernel.numa_balancing=1 (e.g. via sysctl).
