mesa: etnaviv: fix shader miscompilation with more than 16 labels

The labels array may change its virtual address on a reallocation, so
it is invalid to cache pointers into the array. Rather than using the
pointer directly, remember the array index.

Fixes miscompilation of shaders in glmark2 ideas, leading to GPU hangs.

This is a backport from 17.1.5.
