net: ip_gre: Accept IFLA_INFO_DATA-less configuration
[ Upstream commit 32ca98feab8c9076c89c0697c5a85e46fece809d ]
The fix referenced below causes a crash when an ERSPAN tunnel is created
without passing IFLA_INFO_DATA. Fix by validating passed-in data in the
same way as ipgre does.
Fixes: e1f8f78ffe98 ("net: ip_gre: Separate ERSPAN newlink / changelink callbacks")
