sched: walt: Do dequeue task accounting after dequeue

Browse Source 
Until recently, we used to do all the dequeue task accounting business
after the call the dequeue task call was done. However, due to an
upstream change in the position of the trace hook, we modified our value
adds to account for doing this work prior to dequeue task. However,
there were unforeseen consequences as a result. As there is
now an "after" dequeue hook available, it is more intuitive to do this
work after dequeue task has taken place, and furthermore, this keeps the
work in line with the manner in which it is done on prior chipsets
ensuring stability.
