Baokun Li 607d3aab73 jffs2: fix memory leak in jffs2_do_mount_fs 
commit d051cef784de4d54835f6b6836d98a8f6935772c upstream.

If jffs2_build_filesystem() in jffs2_do_mount_fs() returns an error,
we can observe the following kmemleak report:

--------------------------------------------

This is because the resources allocated in jffs2_sum_init() are not
released. Call jffs2_sum_exit() to release these resources to solve
the problem.
