Fix copy-paste typos in DynamicQuantizeLSTM zero-point and scale validation (#29462)
### Description
Two copy-paste typos in DynamicQuantizeLSTM::Compute
( dynamic_quantize_lstm.cc ) cause the recurrence-weight zero-point and
scale to be validated against the wrong tensor's shape:
1. L181: R_zp_shape = w_zp->Shape() → r_zp->Shape() .
ZeroPointCheck then iterates w_zp 's element count over the smaller
r_zp tensor, reading past it (OOB read).
2. L188: WeightCheck(W_scale_shape, R_scale) →
WeightCheck(R_scale_shape, R_scale) . The recurrence scale shape is
validated against the input scale shape instead of its own.
