monitor-dd-progress fix

Browse Source 
stdout if line buffered, thus even it's redirect to stderr, it will not show
on console automaticly. Because monitor_dd_progress is only for rawdump
currently, so I think we can just use "echo" instead of "echo -n".

Another problem is sometimes CURRENT_SIZE does not get value when it's used
in $(($CURRENT_SIZE / 1048576)), fix this issue as well.
