ac/nir: pass the nir variable through tcs loading.

I was going to have to add another parameter to this monster,
so we should just pass the nir_variable in, I can't find any
reason this would be a bad idea.

This needed for the next fix.

Fixes: 94f9591995 (radv/ac: add support for TCS/TES inputs/outputs.)
