migration: Report when bdrv_inactivate_all fails
If the bdrv_inactivate_all fails near the end of the migration, the migration will fail and often the only diagnostics in the log are an I/O error which you can't distinguish from an error on the socket connection. Add an error so we know when it's actually a block problem.
