block-migration: fix pending() and iterate() return values
The return value of .save_live_pending() is the number of bytes

includes dirty blocks but not in-flight bdrv_aio_readv() requests or
unsent blocks. Crucially, it also doesn't include the bulk phase where
the entire device is transferred - therefore we risk completing block
migration before all blocks have been transferred!

transferred this iteration. Currently we return whether there are bytes
remaining, which is incorrect.

Linux block devices can be set read-only with "blockdev --setro

device node permissions. Therefore the device can still be opened
