vti4: ipip tunnel deregistration fixes.
[ Upstream commit 5483844c3fc18474de29f5d6733003526e0a9f78 ]
If tunnel registration failed during module initialization, the module
would fail to deregister the IPPROTO_COMP protocol and would attempt to
deregister the tunnel.
The tunnel was not deregistered during module-exit.
Fixes: dd9ee3444014e ("vti4: Fix a ipip packet processing bug in 'IPCOMP' virtual tunnel")
