drm/i915/gvt: Use an "unsigned long" to iterate over memslot gfns
Use an "unsigned long" instead of an "int" when iterating over the gfns
in a memslot. The number of pages in the memslot is tracked as an
"unsigned long", e.g. KVMGT could theoretically break if a KVM memslot
larger than 16TiB were deleted (2^32 * 4KiB).
