Upstream source description

In the Linux kernel, the following vulnerability has been resolved: md: call __md_stop_writes in md_stop From the link [1], we can see raid1d was running even after the path raid_dtr -> md_stop -> __md_stop. Let's stop write first in destructor to align with normal md-raid to fix the KASAN issue.
