[PATCH 65/86] ipv4: Remove output route check in ipv4_mtu

[Steven Rostedt]

3.6.11.1 stable review patch.
If anyone has any objections, please let me know.

------------------

From: Steffen Klassert <steffen.klassert@xxxxxxxxxxx>

[ Upstream commit 34f48df8ec531943ca83ea994eb2561897d8f9f4 ]

The output route check was introduced with git commit 261663b0
(ipv4: Don't use the cached pmtu informations for input routes)
during times when we cached the pmtu informations on the
inetpeer. Now the pmtu informations are back in the routes,
so this check is obsolete. It also had some unwanted side effects,
as reported by Timo Teras and Lukas Tribus.
