net: vxlan: rename SKB_DROP_REASON_VXLAN_NO_REMOTE

[ Upstream commit 46e0ccfb88f02ab2eb20a41d519d6e4c028652f2 ]

The SKB_DROP_REASON_VXLAN_NO_REMOTE skb drop reason was introduced in
the specific context of vxlan. As it turns out, there are similar cases
when a packet needs to be dropped in other parts of the network stack,
such as the bridge module.

Rename SKB_DROP_REASON_VXLAN_NO_REMOTE and give it a more generic name,
so that it can be used in other parts of the network stack. This is not
a functional change, and the numeric value of the drop reason even
remains unchanged.
