test: fix element annotations in blas/ext/base/zapx ndarray offset tests

Propagates fix from 5d3c84a ("test: fix element annotations in ndarray offset tests") to `zapx`, which shared the same misaligned `// 0` and `// 1` annotations in the offset-parameter test block. With the call `zapx( 2, alpha, x, 1, 1 )`, the iteration visits complex indices 1 and 2 (flat float positions 2-3 and 4-5), so the `// 1` markers move from flat positions 6-7 onto positions 4-5 in both the input and expected complex arrays.
