nir: fix const-cast warning on MSVC

We're casting pointers to const memory to const pointers. MSVC complains
about this with the following warning:

warning C4090: 'initializing': different 'const' qualifiers

In this case, we can easily use both constnesses, because all we do is
read here. So let's avoid the warning by adding another const-keyword.
