tune2fs: do not change j_tail_sequence in journal superblock

The function recover_ext3_journal() in debugfs/journal.c, if the log
replay is over, the j_tail_sequence in journal superblock is not
changed to the value of the last transaction sequence.  This will
cause subsequent log commitids to count from the commitid in last
time.  After tune2fs -e, the log commitid is counted from the commitid
in last time, if the log ID of the current operation overlaps with
that of the last operation, this will cause logs that were previously
replayed by tune2fs to be replayed here.
