Yeah, I incorrectly assumed that bio based drivers would call
blk_init_allocated_queue().  I think we need to move the initial
bypass_end call to blk_register_queue().  Like the following.  Not
completely sure yet tho.

I can confirm that with this patch, hang issue is gone. I tried it on
a dm device.

Thanks, will prep a patch.
