cluster/afr: Handle stack reset failures
When all the bricks go down in the middle of the self-heal, in AFR_STACK_RESET
afr_local_init will fail because all the bricks are down. So local will remain
NULL for the frame. This leads to crashes as this failure is not handled in
both entry and data self-heals.
