Fix a crash that could occur in cdr_csv when mutliple threads tried to close the same file.

Do we actually need the locking here?  What happens if you open the same file twice, and
 two threads try to write to it at the same time?  Is fputs() going to write out the entire
 line at once?  I suspect that it could be possible for the second fopen to run during the
 first fputs, so the position could be in the middle of the previously written line...

Issue 10347, initial patch by explidous (but I removed all of the paranoia stuff..)
