Kristof Provost 3f3e4f3c74 dummynet: don't use per-vnet locks to protect global data. 
The ref_count counter is global (i.e. not per-vnet) so we can't use a
per-vnet lock to protect it. Moreover, in callouts curvnet is not set,
so we'd end up panicing when trying to use DN_BH_WLOCK().

Instead we use the global sched_lock, which is already used when
evaluating ref_count (in unload_dn_aqm()).
