block: default BLOCK_LEGACY_AUTOLOAD to y

As Luis reported, losetup currently doesn't properly create the loop
device without this if the device node already exists because old
scripts created it manually. So default to y for now and remove the
aggressive removal schedule.

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.
