blk-mq: make the blk-mq stacking code optional
The code to stack blk-mq drivers is only used by dm-multipath, and
will preferably stay that way. Make it optional and only selected
by device mapper, so that the buildbots more easily catch abuses
like the one that slipped in in the ufs driver in the last merged
window. Another positive side effects is that kernel builds without
device mapper shrink a little bit as well.
