Spontaneous Summoner says: "You can spontaneously cast summon nature's ally spells (from your class spell list) just as a druid can."
The Druid's Spontaneous Casting ability says: "A druid can channel stored spell energy into summoning spells that she hasn’t prepared ahead of time. She can "lose" a prepared spell in order to cast any summon nature’s ally spell of the same level or lower."
The Spirit Shaman is a spontaneous caster. They don't have any prepared spells to convert into summons.
