ocfs2: fix memory leak in ocfs2_stack_glue_init()
Description

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix memory leak in ocfs2_stack_glue_init() ocfs2_table_header should be free in ocfs2_stack_glue_init() if ocfs2_sysfs_init() failed, otherwise kmemleak will report memleak.
