Subject: [PATCH] tune2fs: exit directly when fs freed in ext2fs_run_ext3_journal

In ext2fs_run_ext3_journal(), fs will be free and reallocate. But
reallocating by ext2fs_open() may fail in some cases, such as device
being offline at the same time. In these cases, goto closefs will
cause segfault, fix it by exiting directly.
