defconfig: 8994: enable CONFIG_DEBUG_SLUB_PANIC_ON

Browse source 
Add the DEBUG_SLUB_PANIC_ON option to KCONFIG preventing
the existing defconfig option from being overwritten
by make config.

This will induce a panic if slab debug catches corruptions
within the padding of a given object.

The intention here is to induce collection of data
immediately after the corruption is detected with
the goal to catch the possible source of the corruption.

help
SLUB has a resiliency feature enabled which restores bytes in
order for production environments to continue to operate. IN
debug options this may not be desirable as it prevents from
investigating the root cause which may be rooted within cache
or memory.
