Revert "block: improve queue_should_plug() by looking at IO depths"

This reverts commit 1737b1cf94bcad49fe06366641d74c6011ecb0cd.

"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.
