[Sheepdog] [PATCH 4/6] remove useless sd_node_list checking in is_master()

[FUJITA Tomonori]

- for non masters, if sys->synchronized is non zero, sys->sd_node_list
  should not be empty.

- for the master, confchg is called before deliver. confchg sets
  sys->synchronized and adds itself to sd_node_list.
