init: set SetKptrRestrict before early-init

As part of debugging long run issue we are enabling
module info as part of debug build under the config key
DEBUG_MODULE_LOAD_INFO , But doing so can lead to info leak
as modules/dlkm are loaded in early-init and setting the
kptr_restriction is done after early-init.

So moving setting of kptr_restrict much before early-init.
