Subject: geneve: Remove socket and offload handlers at destruction.
From: Jesse Gross <[email protected]>
[ Upstream commit 7ed767f73192d6daf673c6d885cd02d5f280ac1f ]
Sockets aren't currently removed from the the global list when
they are destroyed. In addition, offload handlers need to be cleaned
up as well.
Fixes: 0b5e8b8e ("net: Add Geneve tunneling protocol driver")
