eas: eas_big_to_small: fix wrong big{small}_task_us in corner case

sometimes the task running as big was scheduled after "SMALL TASK"
trace marker:

eas_big_to_smal [big core] .... 27284.761959: SMALL TASK
eas_big_to_smal [big core] d..2 27284.761978: sched_switch:
  prev_comm=eas_big_to_small ==> next_comm=swapper/6

the last execution segment of big task is counted as small_task_us
in this case.

after "SMALL TASK" trace marker, the small task will be scheduled
for the first time, mark this time as smalltask_ts_usec can fix
this issue.
