vxlan: simplify if clause in dev_close 

Dan Carpenter's static checker warned that in vxlan_stop we are checking
if 'vs' can be NULL while later we simply derreference it.

As after commit 56ef9c909b ("vxlan: Move socket initialization to
within rtnl scope") 'vs' just cannot be NULL in vxlan_stop() anymore, as
the interface won't go up if the socket initialization fails. So we are
good to just remove the check and make it consistent.
