[ 28/53] ext4: add missing kfree() on error return path in add_new_gdb()

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <error27@xxxxxxxxx>

commit c49bafa3842751b8955a962859f42d307673d75d upstream.

We added some more error handling in b40971426a "ext4: add error
checking to calls to ext4_handle_dirty_metadata()".  But we need to
call kfree() as well to avoid a memory leak.
