sched: Use trace_call__<tp>() to save a static branch

The wrapper functions __trace_set_current_state() and
__trace_set_need_resched() allow the tracepoints to be called from code
outside sched/core.c, those calls are already guarded by a
tracepoint_enabled(<tp>) so there is no need to repeat this check once
again inside the call using trace_<tp>().

Use the new trace_call__<tp>() API to directly call the tracepoint
without check. Those helper functions must be called after the
appropriate check.
