The rcu_poll_gp_seq_end() and rcu_poll_gp_seq_end_unlocked() both check
that interrupts are enabled, as they normally should be when waiting for
an RCU grace period. Except that it is legal to wait for grace periods
during early boot, before interrupts have been enabled for the first time,
and polling for grace periods is required to work during this time.
This can result in false-positive lockdep splats in the presence of
boot-time-initiated tracing.
This commit therefore conditions those interrupts-enabled checks on
rcu_scheduler_active having advanced past RCU_SCHEDULER_INACTIVE, by
which time interrupts have been enabled.
