Marko Zec e9cedda843 MFC r196633:
Introduce a separate sx lock for protecting lists of vnet sysinit
  and sysuninit handlers.

  Previously, sx_vnet, which is a lock designated for protecting
  the vnet list, was (ab)used for protecting vnet sysinit / sysuninit
  handler lists as well.  Holding exclusively the sx_vnet lock while
  invoking sysinit and / or sysuninit handlers turned out to be
  problematic, since some of the handlers may attempt to wake up
  another thread and wait for it to walk over the vnet list, hence
  acquire a shared lock on sx_vnet, which in turn leads to a deadlock.
  Protecting vnet sysinit / sysuninit lists with a separate lock
  mitigates this issue, which was first observed with
  flowtable_flush() / flowtable_cleaner() in sys/net/flowtable.c.
