[PATCH] sched: Fix some spelling mistakes in the scheduler module

[jianyun.gao]

The following are some spelling mistakes existing in the scheduler
module. Just fix it!

  slection -> selection
  achitectures -> architectures
  excempt -> except
  incorectly -> incorrectly
  litle -> little
  faireness -> fairness
  borken -> broken
  condtion -> condition

Best regards !
