Jens Axboe 9676ed4dd1 Revert "block, bfq: honor already-setup queue merges" ...

[ Upstream commit ebc69e897e ]

This reverts commit 2d52c58b9c.

We have had several folks complain that this causes hangs for them, which
is especially problematic as the commit has also hit stable already.

As no resolution seems to be forthcoming right now, revert the patch.
