vxlan: eliminate cached dst leak
[ Upstream commit 35cf2845563c1aaa01d27bd34d64795c4ae72700 ]
After commit 0c1d70af924b ("net: use dst_cache for vxlan device"),
cached dst entries could be leaked when more than one remote was
present for a given vxlan_fdb entry, causing subsequent netns
operations to block indefinitely and "unregister_netdevice: waiting
for lo to become free." messages to appear in the kernel log.
Fix by properly releasing cached dst and freeing resources in this
case.
Fixes: 0c1d70af924b ("net: use dst_cache for vxlan device")
