Revert "ANDROID: gki_defconfig: temporarily disable KFENCE in GKI"

This reverts commit a5631d493c290fee4c2102804d71c21e304fdecf.
Picking  "kfence: await for allocation using wait_event" resulted in
KFENCE spinning no more in toggle_allocation_gate(), which reportedly
fixed the power regression.

Bug: 185280916
Test: power team confirmed there's no regression
