[ Upstream commit c96b6acc8f89a4a7f6258dfe1d077654c11415be ]
There are some memory leaks in dccp_init() and dccp_fini().
In dccp_fini() and the error handling path in dccp_init(), free lhash2
is missing. Add inet_hashinfo2_free_mod() to do it.
If inet_hashinfo2_init_mod() failed in dccp_init(),
percpu_counter_destroy() should be called to destroy dccp_orphan_count.
It need to goto out_free_percpu when inet_hashinfo2_init_mod() failed.
Fixes: c92c81df93 ("net: dccp: fix kernel crash on module load")
