ARM: 8746/1: vfp: Go back to clearing vfp_current_hw_state[]



Commit 384b38b6 ("ARM: 7873/1: vfp: clear vfp_current_hw_state
for dying cpu") fixed the cpu dying notifier by clearing
vfp_current_hw_state[]. However commit e5b61baf ("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 clearing vfp_current_hw_state[].
