nir: Share get_io_offset handling in nir_lower_io.
The load/store/atomic cases all duplicated the get_io_offset code, with
a few tiny differences: stores didn't bother checking for per-vertex
inputs, because they can't be stored to, and atomics didn't check at
all, since shared variables aren't per-vertex.
However, it's harmless to check, and allows us to share more code.
