Revert "migration: don't account sleep time for calculating bandwidth"

This reverts commit 7161082c8d8cf167c508976887a0a63f4db92b51.

Reverting this patch fixes a divide-by-zero error in qemu that can be
fairly reliably triggered by doing block migration. In this case, the
configuration/error was:

This revert potentially re-introduces a bug that was present in 1.4,
but fixes a prevalent issue with block migration so we should revert
it for now and take an updated patch later.
