Describe the bug

The return of method "getRealView" in WXScroller should be 'mRealView', which is mScrollerView now.
When I reduce the children of scroller view, it has no effect now.

To Reproduce

<template>
  <div class="wrapper">
    <scroller class="scroller" v-for="(row) in rows" scroll-direction="horizontal">
      <text>{{row.length}}</text>
      <div v-for="(item, index) in row" class="item">
        <text>{{index + item.name}}</text>
      </div>
    </scroller>
    <div @click="changeData" class="button">
      <text>点击</text>
    </div>
  </div>
</template>

I reduces item of row in function 'changeData', the length of row changed, but the number of children which displayed didn't change.

Environment

• Device: Vivo X9
• OS: Android
• Version 7.1.2
• Build from source no

Expected behavior

The number of children in Scroller view should be reduces on the screen when I reduces the number of items.
