Commit 384b38b66947 ("ARM: 7873/1: vfp: clear vfp_current_hw_state for dying cpu") fixed the cpu dying notifier by using vfp_current_hw_state(). However commit e5b61bafe704 ("arm: Convert VFP hotplug notifiers to state machine") incorrectly used the original vfp_force_reload() function in the cpu dying notifier.
Fix it by going back to the correct vfp_current_hw_state() usage.
