gpu: nvgpu: wakeup semaphores after clearing the interrupt

Currently, 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
