rcu: Update comments for gp_seq and expedited GP tracking

Browse source

Update documentation comments throughout the RCU callback infrastructure
to reflect the transition from a single grace-period sequence number to
the full struct rcu_gp_seq that tracks both normal and expedited grace
periods.

The ->gp_seq[] array documentation in rcu_segcblist.h is updated to
describe dual (normal and expedited) GP tracking.  The
rcu_segcblist_advance(), rcu_segcblist_accelerate(), and
rcu_advance_cbs() comments are updated to refer to the struct rcu_gp_seq
state (gsp) instead of the old bare grace-period sequence number (seq).
