iommu/vt-d: Fix constant-out-of-range warning
On 32-bit builds, the vt-d driver causes a warning with clang:
drivers/iommu/intel/nested.c:112:13: error: result of comparison of constant 18446744073709551615 with expression of type 'unsigned long' is always false [-Werror,-Wtautological-constant-out-of-range-compare]
112 | if (npages == U64_MAX)
| ~~~~~~ ^ ~~~~~~~
Make the variable a 64-bit type, which matches both the caller and the
use anyway.
