MLK-10453 mmc: fix possible unintialized ocr
This commit ca4113da25b42bce44a2e7998966a47352f11613
"mmc: fix OCR Polling"
does not consider cmd structure, and may leave it in uninitialized state.
We can directly use op_cond_response here, since until here,
op_cond_response already get the OCR value from chip.
