vxlan: fix missing options_len update on RX with collect metadata
[ Upstream commit 4024fcf70556311521e7b6cf79fa50e16f31013a ]
When signalling to metadata consumers that the metadata_dst entry
carries additional GBP extension data for vxlan (TUNNEL_VXLAN_OPT),
the dst's vxlan_metadata information is populated, but options_len
is left to zero. F.e. in ovs, ovs_flow_key_extract() checks for
options_len before extracting the data through ip_tunnel_info_opts_get().
Geneve uses ip_tunnel_info_opts_set() helper in receive path, which
sets options_len internally, vxlan however uses ip_tunnel_info_opts(),
so when filling vxlan_metadata, we do need to update options_len.
Fixes: 4c22279848c5 ("ip-tunnel: Use API to access tunnel metadata options.")
