blktrace: add back conversion
Fixup for bz 502889. Problem: when executing with /dev/cciss/foo (long path names) btreplay complains (No such file or directory). Bug: Missed back conversion of erscores to slashes. Solution: Convert underscores to slashes to restore device names that have larger paths. Signed-off-by: Edward Shishkin <edward@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
