[PULL 30/38] migration: Use the number of transferred bytes directly

[Juan Quintela <quintela@redhat.com>]

We only use migration_transferred_bytes() to calculate the rate_limit,
for that we don't need to flush whatever is on the qemu_file buffer.
Remember that the buffer is really small (normal case is 32K if we use
iov's can be 64 * TARGET_PAGE_SIZE), so this is not relevant to
calculations.
