Vadim Fedorenko 5d3007b6cc net: ip_tunnel: fix mtu calculation 
commit 28e104d002 upstream.

dev->hard_header_len for tunnel interface is set only when header_ops
are set too and already contains full overhead of any tunnel encapsulation.
That's why there is not need to use this overhead twice in mtu calc.

Fixes: fdafed4599 ("ip_gre: set dev->hard_header_len and dev->needed_headroom properly")
