Subject: [PATCH net-next] vxlan: remove vni zero check and drop for COLLECT_METADATA

From: Roopa Prabhu <roopa@...ulusnetworks.com>

This patch drops the vni zero check for COLLECT_METADATA mode.
It is not really needed, vni zero is a valid vni.

Fixes: 3ad7a4b141eb ("vxlan: support fdb and learning in COLLECT_METADATA mode"
