[Qemu-trivial] [PULL 01/16] docs: Fix description of the leaky bucket algorithm in throttle.txt

[Michael Tokarev]

From: Alberto Garcia <address@hidden>

Commit 0bab0ebb17759c926bd48fd396bd8cbb2c8e4a3e was supposed to fix
a mistake in the description of the leaky bucket algorithm, but the
version that finally landed after the review process was incorrect.

This patch solves that problem and hopefully clarifies the description
a bit better.

 The bucket is initially empty, therefore water can be added until it's
 full at a rate of 2000 IOPS (the burst rate). Once the bucket is full
