Subject: [PATCH 4.19 06/95] net: ipip: fix wrong address family in init error path

From: Vadim Fedorenko <vfedorenko@...ek.ru>

[ Upstream commit 57ebc8f08504f176eb0f25b3e0fde517dec61a4f ]

In case of error with MPLS support the code is misusing AF_INET
instead of AF_MPLS.

Fixes: 1b69e7e6c4da ("ipip: support MPLS over IPv4")
