KVM: arm64: Fix prototype for __sve_save_state/__sve_restore_state
Since the prototypes for __sve_save_state/__sve_restore_state at
hyp were added, the underlying macro has acquired a third
parameter for saving/restoring ffr.
Fix the prototypes to account for the third parameter, and
restore the ffr for the guest since it is saved.
