net: Fix potential memory leak in proto_register()
[ Upstream commit 0f5907af39137f8183ed536aaa00f322d7365130 ]
If we failed to assign proto idx, we free the twsk_slab_name but forget to
free the twsk_slab. Add a helper function tw_prot_cleanup() to free these
together and also use this helper function in proto_unregister().
Fixes: b45ce32135d1 ("sock: fix potential memory leak in proto_register()")
