Hi,
[ Upstream commit 6ce59025f1182125e75c8d121daf44056b65dd1f ]
The driver allocates queues for all the units it potentially supports. But if we fail to detect any drives, then we fail loading the module without cleaning up those queues. This is now evident with the switch to blk-mq, though the bug has been there forever as far as I can tell.
Also fix cleanup through regular module exit.

This commit causes a new problem. And the commit that made the fix is 58ccd2d31e502c37e108b285bf3d343eb00c235b. I think this commit needs to be applied together.
I've queued up this fix, thank you!
