ADOL-C: do not put the rank into trace_off()
Following the doc at
https://github.com/coin-or/ADOL-C/blob/master/ADOL-C/doc/adolc-manual.pdf
this enforces writing the tapes to disk and has nothing to do with the actual taping. From the doc:
"By setting the optional integer argument file
of trace_off
to 1, the user may force a
numbered tape file to be written even if the tape array (buffer) does not overflow. If the
argument file is omitted, it defaults to 0, so that the tape array is written onto a tape file
only if the length of any of the buffers exceeds [OLVT]BUFSIZE
elements."
