In gk20a_ce2_nonstall_isr(), we first invoke semaphore workqueue
on all channels and then clear the interrupt
This delay in clearing the interrupt can sometimes lead to
dropping of new interrupt
If that happens, we never invoke gk20a_channel_semaphore_wakeup()
for new semaphore interrupts and semaphore waiting
never completes.
Fix this by moving gk20a_channel_semaphore_wakeup() after
we clear the interrupt
