2023-10-31migration: Use migration_transferred_bytes()Juan Quintela
There are only two differnces with the old value: - the amount of QEMUFile that hasn't yet been flushed. It can be discussed what is more exact, the new or the old one. - the amount of transferred bytes that we forgot to account for (the newer is better, i.e. exact). Notice that this two values are used to: a - present to the user b - calculate the rate_limit So a few KB here and there is not going to make a difference.

2023-10-31migration: Use the number of transferred bytes directlyJuan Quintela
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.

2023-10-31migration: Stop migration immediately in RDMA error pathsPeter Xu
In multiple places, RDMA errors are handled in a strange way, where it only sets qemu_file_set_error() but not stop the migration immediately. It's not obvious what will happen later if there is already an error. Make all such failures stop migration immediately.
