KVM: x86/mmu: Avoid memslot lookup during KVM_PFN_ERR_HWPOISON handling

Browse source

Pass the kvm_page_fault struct down to kvm_handle_error_pfn() to avoid a
memslot lookup when handling KVM_PFN_ERR_HWPOISON. Opportunistically
move the gfn_to_hva_memslot() call and @current down into
kvm_send_hwpoison_signal() to cut down on line lengths.

No functional change intended.
