Revert "md-raid: destroy the bitmap after destroying the thread"

commit 1d258758cf06a0734482989911d184dd5837ed4e upstream.

This reverts commit e151db8ecfb019b7da31d076130a794574c89f6f. Because it
obviously breaks clustered raid as noticed by Neil though it fixed KASAN
issue for dm-raid, let's revert it and fix KASAN issue in next commit.
