nir/dead_write_vars: Get modes directly from derefs
Instead of going all the way back to the variable, just look at the
deref. The modes are guaranteed to be the same by nir_validate whenever
the variable can be found. This fixes clear_unused_for_modes for
derefs that don't have an accessible variable.
