trace: events: rcu: Change description of rcu_dyntick trace event The different strings used for describing the polarity are Start, End and StillNonIdle. Since StillIdle is not used in any trace point for rcu_dyntick, it can be removed and StillNonIdle can be added in the description. Because StillNonIdle is used in a few tracepoints for rcu_dyntick. Similarly, USER, IDLE and IRQ are used for describing context in the rcu_dyntick tracepoints. Since, "KERNEL" is not used for any of the rcu_dyntick tracepoints, remove it from the description.
