Over the time many of DMU functions got flags argument to control prefetch, caching, etc. Few functions though left without it, even though closer look shown that many of them do not require prefetch due to their access pattern. This patch adds the flags argument to dmu_write(), dmu_buf_hold_array() and dmu_buf_hold_array_by_bonus(), passing DMU_READ_NO_PREFETCH where applicable. I am going to also pass DMU_UNCACHEDIO to some of them later.
