f2fs: fix incorrect multidevice info in trace_f2fs_map_blocks()
When f2fs_map_blocks()->f2fs_map_blocks_cached() hits the read extent
cache, map->m_multidev_dio is not updated, which leads to incorrect
multidevice information being reported by trace_f2fs_map_blocks().
This patch updates map->m_multidev_dio in f2fs_map_blocks_cached() when
the read extent cache is hit.
