JFS: fix memleak in jfs_mount

[ Upstream commit c48a14dca2cb57527dde6b960adbe69953935f10 ]

In jfs_mount, when diMount(ipaimap2) fails, it goes to errout35. However,
the following code does not free ipaimap2 allocated by diReadSpecial.

Fix this by refactoring the error handling code of jfs_mount. To be
specific, modify the lable name and free ipaimap2 when the above error
ocurrs.

Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
