nir: Fix deref offset calculation for structs. 

We were calcuating the offset for the field within the struct, and just
dropping it on the floor.  Fixes a regression in
KHR-GLES3.shaders.struct.local.nested_struct_array_dynamic_index_fragment
and a few of its friends since the scratch lowering commit.

Fixes: e8e159e9df ("nir/deref: Add helpers for getting offsets")
