rcu/tasks: Update rtp->tasks_gp_seq comment
The rtp->tasks_gp_seq grace-period sequence number is not a strict count,
but rather the usual RCU sequence number with the lower few bits tracking
per-grace-period state and the upper bits the count of grace periods
since boot, give or take the initial value. This commit therefore
adjusts this comment.
