intel_iommu: Fix mask may be uninitialized in vtd_context_device_invalidate
With -Werror=maybe-uninitialized configuration we get
../hw/i386/intel_iommu.c: In function ‘vtd_context_device_invalidate’:
../hw/i386/intel_iommu.c:1888:10: error: ‘mask’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]
1888 | mask = ~mask;
| ~~~~~^~~~~~~
Add a g_assert_not_reached() to avoid the error.
