rcu: Rename dynticks_completed to completed_fqs



This field is used whether or not CONFIG_NO_HZ is set, so the
old name of ->dynticks_completed is quite misleading.

Change to ->completed_fqs, given that it the value that
force_quiescent_state() is trying to drive the ->completed field
away from.
