KVM: x86/xen: Use hva_t for holding hypercall page address

Use hva_t, a.k.a. unsigned long, for the local variable that holds the
hypercall page address.  On 32-bit KVM, gcc complains about using a u64
due to the implicit cast from a 64-bit value to a 32-bit pointer.

  arch/x86/kvm/xen.c: In function ‘kvm_xen_write_hypercall_page’:
  arch/x86/kvm/xen.c:300:22: error: cast to pointer from integer of
                             different size [-Werror=int-to-pointer-cast]
  300 |   page = memdup_user((u8 __user *)blob_addr, PAGE_SIZE);
