KVM: arm64: Remove extra argument for __pvkm_host_{share,unshare}_hyp()

__pvkm_host_share_hyp() and __pkvm_host_unshare_hyp() both have one
parameter, the pfn, not two. Even though correctness isn't impacted because
the SMCCC handlers pass the first argument and ignore the second one, let's
call the functions with the proper number of arguments.
