Javen Wu a47587389e Drop spill buffer reference 
When calling sa_update() and friends it is possible that a spill
buffer will be needed to accomidate the update.  When this happens
a hold is taken on the new dbuf and that hold must be released
before calling dmu_tx_commit().  Failing to release the hold will
cause a copy of the dbuf to be made in dbuf_sync_leaf().  This is
done to ensure further updates to the dbuf never sneak in to the
syncing txg.

This could be left to the sa_update() caller.  But then the caller
would need to be aware of this internal SA implementation detail.
It is therefore preferable to handle this all internally in the
SA implementation.
