rcu: Remove full memory barrier on boot time eqs sanity check
When the boot CPU initializes the per-CPU data on behalf of all possible
CPUs, a sanity check is performed on each of them to make sure none is
initialized in an extended quiescent state.
This check involves a full memory barrier which is useless at this early
boot stage.
Do a plain access instead.
