Summary WebView::backingStore should check if m_backingStoreBitmap is NULL

There are cases when WebView::backingStore is called while m_backingStoreBitmap is NULL, such as after deleteBackingStore has been called in response to a WM_NCACTIVATE message (indicating a change in the the active/inactive state). Instead of attempting to dereference a null pointer, we should return early with E_FAIL if m_backingStoreBitmap is NULL.
