Jens Axboe 79da0644a8 Revert "block: improve queue_should_plug() by looking at IO depths"
This reverts commit fb1e75389b.

"Benjamin S." <sbenni@gmx.de> reports that the patch in question
causes a big drop in sequential throughput for him, dropping from
200MB/sec down to only 70MB/sec.

Needs to be investigated more fully, for now lets just revert the
offending commit.
