tool_progress: Fix progress meter in parallel mode

Make sure the total amount of DL/UL bytes are counted before the
transfer finalizes. Otherwise if a transfer finishes too quick, its
total numbers are not added, and results in a DL%/UL% that goes above
100%.

Detail:

progress_meter() is called periodically, and it may not catch a
transfer's total bytes if the value was unknown during the last call,
and the transfer is finished and deleted (i.e., lost) during the next
call.
