hw/i386/intel_iommu: vtd_slpte_nonzero_rsvd(): assert no overflow

We support only 3- and 4-level page-tables, which is firstly checked in
vtd_decide_config(), then setup in vtd_init(). Than level fields are
checked by vtd_is_level_supported().

So here we can't have level out from 1..4 inclusive range. Let's assert
it. That also explains Coverity that we are not going to overflow the
array.
